Greetings,
I've been looking through the mailing list archives and I've noticed that
a lot of people have been experiencing the damn SCSI problems that I have
been having recently.
I'm currently running FreeBSD 2.2.1-RELEASE on a P166 with 128MB RAM, an
Adaptec 2940 UW controller, 2 Quantam Atlases, 1 Quantam Grand Prix and an
IDE Quantum Sirocco.
The machine will lock up periodically, giving SCSI drive errors. Here's
the errors I've been getting, the error as reported in /var/log/messages
and a copy of my dmesg output:
sd1(ahc0:5:0): UNIT ATTENTION asc:29,1 retires: 4
SCB: 0x1 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0
SEQADDR == 0x4

I've seen lots of discussion, but not solution on the lists. Has one been
found? Any help would be appreciated.
Thanks in advance,
