Description Sam Varshavchik 2004-02-11 02:57:01 UTC
Description of problem:

Adaptec 29320 in a dual Opteron box, with a pair of 36GB Ultra320
Seagate Cheetahs.

aic79xx.o consistently crashes at system boot time if I allow it to
autonegotiate 320MB/s.

Forcing the aic79xx.o to downshift to 160MB/s, via the card's BIOS (by
disabling packetization and QAS) allows the card to operate normally.

Kernel 2.4.22-1.2166

Both SMP and UP kernels crash.

Boot logs follow.

System boot crash in aic79xx.o

This is the default setting of the 29320 adapter, which autonegotiates 320MB/s.

Forcing the 29320 down to 160MB/s succesfully boots the system.

If I go into the 29320's BIOS setup, and manually turn off packetization and
QAS settings for both SCSI disk drives, the card ramps down to 160MB/s, and the
system boots normally.

I am not able to duplicate this on a Athlon64 system using the 29320.
 Asus K8V Delux mainboard.  Adaptec card negotiates to full 320 speed.
 Will continue to test on other amd64 platforms.
