AIC79XX PCI-X SCSI mystery

AIC79XX PCI-X SCSI mystery

[Bjarne Thomsen]

I have a dual Opteron Tyan MB (S2885) with 4 PCI-X slots.
The 2 first slots can work up to 100 MHz, the last 2 up to 66 MHz.

I have 2 PCI-X Adaptec SCSI controllers: 29160 and 39320A.
A SCSI disk is connected to port A on the 39320A.

When I mount the 39320A in any of the 4 slots the system hangs
after a few seconds (with no error messages in syslog) when I
copy a directory with many files to the SCIS disk.

However, when I mount both controllers in either slots 1 and 2
or slots 3 and 4 I can copy 25GB of files without any hang-up.

I need some help to figure this out. It is a mystery to me.

2.6.22-2mdv #1 SMP Mon Jul 23 17:24:30 CEST 2007 x86_64 AMD Opteron(tm)
Processor 244 GNU/Linux

I do not wish to clutter this mail with random listings,
but I can supply output if somebody can tell me what is needed.

Could it be FW in 29160 is more new than that in 39320A?
and when two cards installed, only one FW is executed...

I had installed the latest firmware (2003) from the Adaptec download
site. Maybe the SCSI dmesg with the verbose option for both drivers
turned on can help. Both controllers are inserted, and a SCSI disk
is connected to the 39320A controller:
