<p>This errata document contains “late-breaking news” about FreeBSD
|
|
7.2-RELEASE. Before installing this version, it is important to consult this document to
|
|
learn about any post-release discoveries or problems that may already have been found and
|
|
fixed.</p>
|
|
|
|
<p>Any version of this errata document actually distributed with the release (for
|
|
example, on a CDROM distribution) will be out of date by definition, but other copies are
|
|
kept updated on the Internet and should be consulted as the “current errata”
|
|
for this release. These other copies of the errata are located at <a
|
|

|
|
target="_top">http://www.FreeBSD.org/releases/</a>, plus any sites which keep up-to-date

mirrors of this location.</p>
|
|
|

<p>Source and binary snapshots of FreeBSD 7-STABLE also contain up-to-date copies of this

document (as of the time of the snapshot).</p>

<p>[20090501] Some machines do not recognize the i386 disc1 as bootable and fall through
|
|
to booting off the next boot device. All affected machines did see the other discs as
|
|
bootable. As a workaround, you can boot using the bootonly or livefs CDROM and then swap
|
|
in disc1 once <a

Notice to fix this problem is planned after the release.</p>

<p>[20090505] A bug was found in the <a

<p>[20090507] A bug was found in the <a

|

class="CITEREFENTRY"><span class="REFENTRYTITLE">fxp</span>(4)</span></a> driver. This
|
|
would cause poor TCP performance when TSO is enabled, and the receiver has a smaller MSS
|
|
than the interface MTU setting. To workaround this issue, one can disable TSO by using <a

|
system). An Errata Notice to fix this problem is planned after the release.</p>

<p>[20090608] An issue was found in the <a
