Hi, 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. Many thanks, Borislav
