I couldn't get the machine to come up with 2.4.32, 2.4.30, or 2.4.27.  It 
was hanging and then throwing the SCSI errors below.  The machine did come 
up with a vanilla 2.6.14.4 and appears to be working fine.  I'm going to 
leave it up over the weekend and see if it oopses.  If it would help, I 
can mail out the .config for the 2.4.32 and 2.6.14.4 builds, or provide 
other information of interest.

-Chris
