Using Linux 2.4.19-pre2-ac3 #1 SMP Sat Mar 9 06:44:19 EST 2002 i686 unknown
Dual 1GHz PIII
Adaptec 39160 on 64-bit PCI -- one chassis on one channel -- 2nd chassis on
2nd channel
2nd Adaptec 39160 has seperate 3-disk RAID set on one channel and tape drive
on 2nd channel (still running fine).
11 Seagate 180GB disks in software RAID5 config (note that "Array Size"
below looks suspicious -- overflowing?. also -- why 13 disks when only 12
requested?)
Partitions are:

(note -- remainder of this not available as it's locked up at this point
trying to access the devices while SCSI reset is still happening)
Was getting oopses when RAID chassis were on seperate 39160's (already
emailed to this list) -- now that both chassis are on one controller am
getting SCSI error when I put both RAID chassis on one controller (still
seperate channels though).
Here's the beginning of the messages from messages (note that md3 finishes
syncing -- since I'm getting constant lockups everybody has to resync -- and
what's with the 0xff messages??):

I'm thinking the next thing I'll do is drop the bus speed to 80MB instead of
160MB and see if it behaves better. Since nothing happened until one of the
other resyncs finished and the raid5 daemon started using 100% CPU on this
raid setup (and the I/O speed increased). Could be we're just banging the
data bus too hard?
