Hi there,
Can anyone provide some insight into what's going on here?
Christoph suggested I ask here; I've also tried out Linus'
current -bk tree (2.6.10-rc3) without luck, same problem.
I'm happy to try out patches, etc.
thanks!

Subject: SCSI oddity
Hi guys,
We recently got an ia32 machine for XFS performance testing which
has 2 Adaptec SCSI disk drives. Not sure exactly which model(s)
yet. When I boot sles9-sp1 and/or 2.6.9 vanilla, bootup takes ages
because of some kind of probing of these devices. Once that is
finally done, the drives perform terribly ... I can't get >3MB/s
out of them. It seems this probing has something to do with it,
looks like its trying to select some default parameters? Have
you seen anything like this before? Here's dmesg, proc/scsi, etc
if it helps.. any tips on how to fix this?
(the user/curr/goal stuff in the /proc dump below seems to show
the wierdness -- user=320,curr/goal=3.3? what is that?)
I also have a couple of local IDE disks, and they consistently
hit around 50-55MB/sec (all measurements here are just raw device
direct reads, using a 64k buffer size).
thanks!

Hi Nathan,
I have seen this problem before with an adaptec U320 controller. The problem
was caused by using a Ultra160 cable on a Ultra320 controller and disk. The
kernel driver for some reason reacted really strange.
The fix I found was to go into the scsi BIOS and set the bus speed from 320
(or it might be max/auto) to 160 and it worked fine. Of course this means
you'll be in Ultra160 mode. Onec the kernel booted (somtimes 10 mintues
later) disk access worked, just very slow, like you reported 3mb/sec tops.
Regards,
Paul

Yep, I have a U320 controller also and a cable that claims to
be U320 capable as well. After reading your suggestion, I've
been trying different settings in the BIOS and using 160 on just
the 1st channel seems to completely stop these probes/scans from
happening (for all channels, oddly enough), and gets the drives
both up to doing ~65MB/sec direct reads now (hooray!), which is
more like what I'd expected.
