Hi everyone,
I just built a nice new SMP box from an Abit BP6 and two 400s [not
overclocked]. I have an Adaptec 2940UW driving a Quantum 3.2gb
UltraSCSI3, Quantium 6.4gb UltraSCSI3, and a Toshiba 12X CDROM. When the
system is under heavy load, everything will freeze for some time [10
seconds?] and the light on the SCSI card will stay on. After a
certain amount of time this settle back to normal. Then it happens
again.
Sometimes sysklogd eats up 99% of a CPU. I looked in Debian
bug reports and saw that this was already known.
I remember reading that the BP6 has IRQ issues. Maybe I need to move
stuff around in my slots.
When I dmesg:

It seems like this only happens when I am heavily utilizing the first
drive and something is accessed off the second drive. I disabled TCQ
[using 2.2.12, btw]. I was running this setup on an Abit BM6 before with
no trouble so I don't think its the SCSI card. Here is any information
so that someone could possibly help me?

Sorry for such a long message, but I'd really like to find the problem and
fix it. Others have had this issue too, I remember. Thanks.
