Hi,
I'm running FreeBSD 4.1.1 on an HP Vectra XU 5/90 machine (Dual P133).
I have 3 SCSI HD's running off the on-board AMD 53c794 (amd0) controller.
I have built a custom kernel, which is just GENERIC with the devices I
don't have commented out, and SMP turned on.
Occasionally the whole SCSI system seems to lock up. The hard drive
light turns on solid, and any process that tries to access any disks
freezes. The rest of the machine is still responsive, until each process
locks up when it eventually accesses the disks. Rebooting solves the
problem. I have let the machine sit in this frozen state for roughly 12
hours to see if it would unfreeze itself. It never does.
I can easily reproduce the problem. If all filesystems are dirty when I
boot, the same problem will occur when fsck tries to check all the
filesystems. I have worked around this (for now) by telling fsck to check
one filesystem at a time. However, the drives still lock up occasionally
under normal use.
As far as I know, the bus is terminated correctly, all drives have
proper IDs, etc. The same hardware was working properly in Linux before I
switched to FreeBSD.
Does anyone have any ideas as to what might be causing the problem, or
where I should look for more information that may help? I've posted dmesg
output below.
Thanks,
Richard Glidden
