Re: AIC7xxx kernel problem with 2.4.2[234] kernels

[Stephen Smoogen <smoogen@lanl.gov>]

Hopefully this wont spark more contention, but here is the additional
info I have dug up:

The cabling goes from the onboard scsi card to a removable carrier tray
to another disk to a terminator. Cabling was pulled out and looked at
for cuts, breaks, and other possible problems.. none seen.

Putting in the debug options Justin sent in a seperate email.. I dont
get much more data.
