I tried 2.5.70-mm1 on the dual celeron at home.  This one has
scsi instead of ide, so I guess it is a RAID-1 problem.
This machine has root on raid-1 too.  I believe there where
several oopses in a row, I captured all of the last one
thanks to a framebuffer with a small font. Here it is:

Unable to handle kernel paging request at virtual address 8a8a8ab6

This looks very similiar to the partial trace
from the ide machine,
it had everything from _end_that_request_first
down to the three default_idles, but with ide
instead of scsi functions.
