I sent this message to -questions earlier, but nobody seems to know about
my problem:
I just recently tried putting an adaptec 2940w SCSI controller into my
FreeBSD machine (running -STABLE cvsupped and recompiled every night at
1:30AM) and since including the driver in my kernel I've noticed some
random panics. Most of the time they occur during heavy disk activity, and
usually only when I'm running X (hence the reason I couldn't tell you the
panic message). Even wierder still, I don't even have any SCSI devices
connected yet; I'm using only IDE disks connected via the motherboard's
builtin ATA66. I have also searched the various FreeBSD mailinglist
archives and found some people with the same problems I was having, but no
solutions. Crashes do not occur in Windows with this configuration (at
least not any more than usual :-) ) and when I take the ahc driver out of
the kernel, the panics stop. I've included my dmesg -v output and my
kernel config file, please let me know if anything else is needed.
