After a normal shutdown the machine would panic on startup right after
trying to mount /.  Note that this happened after a *normal* shutdown.
Kernel was 2.4 from CVS a couple of days ago.  The machine is a Supermicro
SuperServer 5011E.  My testing reveals that having ACPI and APM enabled
causes the problem.  By disabling these (both in the BIOS and the kernel)
the problem went away.

I looked at what was created in lost+found and was easily able to put
things back in the right places.  Just the highest level directory
structure had been lost (i.e. the connections to /) so it was easy to just
mv 3145688 /etc.

No oops or anything.  A complete description of the hardware is at
www.supermicro.com.  I did a shutdown -h now and on restarting it the
machine paniced right after mounting /.  The kernel is checked out from
CVS as of a few days ago.
