cp from SATA to SCSI freeze

cp from SATA to SCSI freeze

[Bjarne Thomsen]

When I copy a directory containing about 6Gb of files
from a SATA disk to my SCSI system disk the system freezes
so I have to press the reset button. This happens with
cp -r, but is does not happen with mv. cp -r works fine
from the SCSI to the SATA disk. The problem reproduces
every time I try to cp from SATA to SCSI.

Is this a known issue?

OS: Mandrake 2.6.8.1-12.5mdksmp x86_64 2 AMD Opteron(tm) Processors
MB: Tyan S2885 Thunder K8W
SCSI IF: Adaptec 29160
Advanced Micro Devices|AMD-8131 PCI-X
Advanced Micro Devices|K8 [Athlon64/Opteron]
sata_sil: Silicon Image|Sil3114A Serial ATA
aic7xxx : Adaptec|7892A

Is there something that I can to to locate the
problem?

When it freezes, do you see some kernel messages displayed on
the console ?

Also, how many SATA disks and how many SCSI disks are involved ?
Are you using software RAID ?

No message of any kind.

2 SCSI disks on the same 29160 controller.

No software raid.

Have the latest BIOS?  BIOS update seems to fix most of the system 
freeze issues, and replacing cables / power often fixes the rest.

Tried booting with "noapic" or "pci=biosirq" or "acpi=off" or "pci=noacpi"?

Yes, I have the latest BIOS (beta), but I didn't use it.
This morning I had an idea: could it be hyper transport?
The CPU2, PCI-X0, and AGP HT Link speeds were set to
600MHz or 800MHz by default.
After having changed all 3 values to 200MHz I
have not had a single freeze. I am still testing.
