I compiled the machine without smp, and then ran things that would tax the
scsi card/drive. Such things as untar'ing kernel sources, doing ls -laR's
of the entire drive, moving files accross partitions, to name a few.
During this I got the following data printed to my console.

When I compile 2.0.32 with SMP, I get the following error upon bootup, when
it does the Partition Check.
VFS: Cannot open root device 08:01
Kenel panic: VFS: Unalbe to mount root fs on 08:01
However, if I cimpile 2.0.32 without SMP support or I compile 2.1.76 with
or without SMP support I don't get this message. I still do get the SCSI
errors with 2.1.76 however.
