<para>For block sizes of 8K and larger, everything should be
limited by the 2G-1 limit on fs block numbers, but is actually
limited by the 1G-1 limit on fs block numbers, except under
-STABLE triple indirect blocks are unreachable, so the limit is
the maximum fs block number that can be represented using
double indirect blocks (approx. (blocksize/4)^2 +
(blocksize/4)), and under -CURRENT exceeding this limit may
cause problems. Using the correct limit of 2G-1 blocks does
cause problems.</para>

<para>You can boot by specifying the kernel directly at the second
stage, pressing any key when the | shows up before loader is
started. More specifically, you have upgraded the source for
your kernel, and installed a new kernel builtin from them
<emphasis>without making world</emphasis>. This is not
supported. Make world.</para>
<para>Because your world and kernel are out of synch. This
