I am having trouble with the aic7xxx driver with Doug Ledford's patches.
Yesterday I upgraded to p7 after shipped 2.0.33 gave me lots of scsi

The machine was in use and went from a normal load < 1.0 up to 10 and kept
going in just a few seconds. It happened several times after a random
amount of uptime, under varying programs - all inside X is about the only

These are the messages from the console:

SCSI host 0 channel 0 reset (pid 15152) timed out trying harder
SCSI bus is being reset for host 0 channel 0 (SCSI 0:0:1:1)
Waiting List inconsistency; SCB index = 255, numscbs = 30 (SCSI 0:0:1:1)
Yikes!! There is a loop in the disconnected list! (SCSI 0:0:1:1)
Yikes!! There is a loop in the free list!

This looped infinitely (well, at least until I dropped the power).

aic7xxx is included in the kernel - not modular. SCB paging was enabled,
but no other changes were made to the default configuration for the board.

The board is a 2940UW installed in a Gateway P200 machine. There is only a
single drive on the board, a Seagate 9gb UW. The machine also has an ide
drive and an ATAPI cdrom which were not mounted at the time, and a 3c900
card in 10MB mode. It is not an NFS server.

Any ideas how I can resolve these problems and make this machine usable?
