I've been running FreeBSD 3.0-980426-SNAP on a tyan with dual ppro 200's
for a month or so now ... Today, I tried to install a buslogic (BT-958)
card into the system. After trial and error, I found that if
SMP support is enabled in the kernel (including a kernel built off
SMP-GENERIC), accessing any device off the scsi chain doesn't work at all...
It works perfectly fine with a non-SMP kernel, however.
Is this a known problem (I searched and didn't find anything)? If not,
I'll do my best to help track down the problem. I'll include dmesg
and mptable stuff below to get started. I don't have a dmesg from
a kernel with the BL driver installed handy, though. I guess
that would help :) I'll provide that as soon as I can. TIA!
