I'm been running some tests on a machine I'm going to set up as my RAID'd
file server, and one of the configurations I'm trying consistently hangs
solid.  The machine is running 1.5.2 on i386, an Athlon on an Abit KT7-RAID
motherboard, most recent motherboard bios.  I'm using 6 drives to form the
RAID, identical scsi disks.  One of my test configurations was to have the
drives split across two bt-948 controllers, 3 on each.

The test I'm doing is using a script Luke Mewburn posted on tech-perform,
http://mail-index.netbsd.org/tech-perform/2001/09/04/0001.html, which
essentially times the extract of pkgsrc.tar.gz on a filesystem mounted
different ways.  With both buslogic controllers in use, the machine hangs
in the middle of a newfs of the partition.  If I take one out, the machine
has no problems with the test, and it doesn't matter which one is in the
machine.  The hangs happen with the drives set at 10 or 20 MB/s, and it
is working fine on a single controller at 20MB/s.  I also tried a test
with both controllers in, but all the drives on one controller and that
had no problems either (the tests ran for hours, versus the minutes the
machine stays up with drives distributed across two controllers).  The
two buslogic controllers are set up such that they're using separate
IRQs.

Given what I've tried, the options left that could be a problem are the
motherboard, the driver or the buslogic boards conflicting.  Has anyone
else seen this, have any thoughts about it?
