I bought an Adaptec 2940UW card about a month ago and I've had three
kernel panics spaced more than a week apart (2.4.19).  After the 2nd
crash I hooked up a serial console and it registered  the following
messages,

Kernel panic: HOST_MSG_LOOP with invalid SCB 2

In interrupt handler - not syncing=20

the only messages before those two were bootup and ppp messages.
After reading some older kernel list e-mails about write combining
(this is a old VIA chipset) I installed
aic79xx-linux-2.4-20030122-tar.gz into a fresh 2.4.21-pre4 tree
compiled and rebooted I haven't had any problems, I'll just have to
wait a couple weeks and see what happens.  Now I'm getting some error
messages on bootup I didn't get previously and I would like to know if
I should ignore them or not.  I have one IDE harddrive, one IDE cdrom,
one SCSI harddrive, and one SCSI cdrom.

Current boot messages
