<p>(31 Oct 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=re&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">re</span>(4)</span></a> and <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=em&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">em</span>(4)</span></a> drivers may
behave poorly under heavy load. In particular, there are reports of <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=em&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">em</span>(4)</span></a> on the IBM
ThinkPad T40 locking up under such conditions.</p>
<p>(31 Oct 2004) There are reports of the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sk&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">sk</span>(4)</span></a> driver locking
up under heavy load, especially when ASUStek on-board NICs are used. To clear the
condition, bringing the interface down then back up and/or rebooting the system may be
needed.</p>
<p>(31 Oct 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=burncd&sektion=8&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">burncd</span>(8)</span></a>
utility is functional but may behave erratically on some systems. Reported symptoms
include that <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=burncd&sektion=8&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">burncd</span>(8)</span></a> can
appear to hang and never complete while the operation actually does complete, and the
progress indicator does not show the correct value. Workarounds include:</p>
<ul>
<li>
<p>Eject and re-insert the media after burning a CD.</p>
</li>
<li>
<p>Press Ctrl-C when <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=burncd&sektion=8&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">burncd</span>(8)</span></a>
appears to hang up while the access LED goes inactive.</p>
</li>
</ul>
<p>(31 Oct 2004) When the user/group rule clauses in <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=pf&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">pf</span>(4)</span></a> and <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a> are
used, the loader tunable <var class="VARNAME">debug.mpsafenet</var> must be set to <var
class="LITERAL">0</var> (this is <var class="LITERAL">1</var> by default). For example,
the following rules are affected:</p>
<p>for <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a>:</p>
<pre class="PROGRAMLISTING">
count ip from any to 192.168.2.1 uid root
</pre>
<p>for <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=pf&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">pf</span>(4)</span></a>:</p>
<pre class="PROGRAMLISTING">
block log quick proto { tcp, udp } all user root
</pre>
<p>To set <var class="VARNAME">debug.mpsafenet</var> to <var class="LITERAL">0</var> on
every boot, add the following line into <tt class="FILENAME">/boot/loader.conf</tt>:</p>
<pre class="PROGRAMLISTING">
debug.mpsafenet=0
</pre>
<p>More specifically, the <var class="LITERAL">group</var> and <var
class="LITERAL">user</var> filter parameters in <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=pf&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">pf</span>(4)</span></a>, and the <var
class="LITERAL">gid</var>, <var class="LITERAL">jail</var>, and <var
class="LITERAL">uid</var> rule options in <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a> are
affected. If <var class="VARNAME">debug.mpsafenet</var> is set to <var
class="LITERAL">1</var>, the system can hang when the rule is evaluated due to a lock
order reversal with the socket layer. More details can be found in the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=8&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(8)</span></a> and <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=pf.conf&sektion=5&manpath=FreeBSD+5.3-stable">

manual pages.</p>
<p>(31 Oct 2004, updated on 12 Nov 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=vinum&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">vinum</span>(4)</span></a>
subsystem works on 5.3, but it can cause a system panic at boot time. As a workaround you
can add <var class="LITERAL">vinum_load="YES"</var> to <tt
class="FILENAME">/boot/loader.conf</tt>.</p>
<p>As an alternative you can also use the new <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=geom&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">geom</span>(4)</span></a>-based <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=vinum&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">vinum</span>(4)</span></a>
subsystem. To activate the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=geom&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">geom</span>(4)</span></a>-aware
vinum at boot time, add <var class="LITERAL">geom_vinum_load="YES"</var> to <tt
class="FILENAME">/boot/loader.conf</tt> and remove <var
class="LITERAL">start_vinum="YES"</var> in <tt class="FILENAME">/etc/rc.conf</tt> if it
exists.</p>
<p>While some uncommon configurations, such as multiple vinum drives on a disk, are not
supported, it is generally backward compatible. Note that for the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=geom&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">geom</span>(4)</span></a>-aware
vinum, its new userland control program, <tt class="COMMAND">gvinum</tt>, should be used,
and it is not yet feature-complete.</p>
<p>(31 Oct 2004) The results of <tt class="COMMAND">netstat -m</tt> can become incorrect
on SMP systems when <var class="VARNAME">debug.mpsafenet</var> is set to <var
class="LITERAL">1</var> (default). This is an error in the statistics gathering because
of a race condition in the counters, not an actual memory leak.</p>
<p>(31 Oct 2004, updated on 5 Nov 2004) For FreeBSD/i386 and FreeBSD/amd64, when
installing FreeBSD 5.3 using an USB keyboard the keyboard will stop working once the
kernel boots, because a PS/2 keyboard is always considered to be attached. As a
workaround, select ``Escape to loader prompt'' in the boot loader menu and enter the
following lines at the prompt:</p>
<pre class="SCREEN">
set hint.atkbd.0.flags="0x1"
boot
</pre>
<p>Note that if you use the boot floppies, this is set by default.</p>
<p>After the installation, add the following line to <tt
class="FILENAME">/boot/loader.conf</tt>:</p>
<pre class="PROGRAMLISTING">
hint.atkbd.0.flags="0x1"
</pre>
<p>(1 Nov 2004) The ULE scheduler described in the release notes has been completely
disabled to discourage its use because it has stability problems.</p>
<p>(1 Nov 2004) Programs linked with <b class="APPLICATION">libpthread</b> may not report
any CPU usage statistics according to <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=top&sektion=1&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">top</span>(1)</span></a>, while those
linked with <b class="APPLICATION">libthr</b> show the correct statistics.</p>
<p>(1 Nov 2004) ATA RAID support for the CMD649 and SiI0680 ATA controllers is
non-functional in this release. When such a controller is brough up under <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ata&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">ata</span>(4)</span></a> (ataraid) on
5.3, the RAID configuration stored under 5.2 or prior may be corrupted.</p>
<p>(3 Nov 2004) For FreeBSD/i386 and FreeBSD/amd64, SMP support in the <tt
class="FILENAME">GENERIC</tt> kernel has been disabled by default because the SMP kernel
can degrade the performance on UP machines. A kernel configuration file <tt
class="FILENAME">SMP</tt>, which can be used to enable SMP support, has been added. More
details on building the custom kernel can be found at <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html"
target="_top">http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html</a>.</p>
<p>(4 Nov 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=tar&sektion=1&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">tar</span>(1)</span></a> utility (also
known as <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=bsdtar&sektion=1&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">bsdtar</span>(1)</span></a>) does
not detect the end of media such as tape and floppy disk properly when it is specified
with the <var class="OPTION">-f</var> option. As an alternative <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=gtar&sektion=1&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">gtar</span>(1)</span></a> (<b
class="APPLICATION">GNU tar</b>) can be used.</p>
<p>(9 Nov 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=geom&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">geom</span>(4)</span></a>-aware <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=vinum&sektion=4&manpath=FreeBSD+5.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">vinum</span>(4)</span></a>
subsystem does not work for RAID5 volumes on machines with a single processor. The
configurations other than RAID5 (such as RAID1) should work correctly. This problem has
been fixed on the RELENG_5 branch.</p>
<p>(9 Nov 2004) The FreeBSD 5.3-RELEASE Migration Guide should have stated that <tt
class="FILENAME">/usr/sbin/nslookup</tt> and <tt class="FILENAME">/usr/sbin/nsupdate</tt>
included in <b class="APPLICATION">BIND 8</b> have to be removed during the source-based
upgrade procedure.</p>
<p>(9 Nov 2004) The FreeBSD 5.3-RELEASE Release Notes should have stated that <a
href="http://www.FreeBSD.org/cgi/url.cgi?ports/net/mpd/pkg-descr"><tt
class="FILENAME">net/mpd</tt></a> which was compiled on the old systems prior to
5.3-RELEASE must be recompiled.</p>
<p>(10 Nov 2004) The FreeBSD 5.3-RELEASE Release Notes should have stated explicitly that
ports/packages which were built on the old systems prior to 5.3-RELEASE and linked with
the old POSIX thread libraries (<b class="APPLICATION">libc_r</b> or <b
class="APPLICATION">libkse</b>) can cause an error ``Spinlock called when not threaded.''
at run time. This happens when the program is linked with multiple different threading
libraries (typically the older ports will be linked with <b
class="APPLICATION">libc_r</b>, while newer ports will be linked with <b
class="APPLICATION">libpthread</b>). Either recompile the ports/packages or add the
necessary lines to <tt class="FILENAME">/etc/libmap.conf</tt>. More details can be found
in <tt class="FILENAME">/usr/src/UPDATING</tt> (20040303 and 20040130).</p>
<p>(12 Nov 2004) The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=em&sektion=4&manpath=FreeBSD+5.3-stable"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">em</span>(4)</span></a> driver behaves
incorrectly when the VLAN support and promiscuous mode are enabled at the same time. A
fix is being tested and will be merged to the 5.3 errata branch.</p>
