This is on a Dell PowerEdge 6300. It has two Adaptec AIC-7890, one
Adaptec AIC-7860, and an AMI MegaRAID controller. There's nothing on
the 7890s, a CDROM and a tape drive on the 7890.
With all of the above enabled the kernel boots with no problems.
However, if I disable the two 7890s from the BIOS (to save 30 seconds
of boot time), I get an oops.
I'm attaching the decoded oops, the boot log from a successful boot
and my .config. Let me know if any other info is needed.
