We have several Kernel Panics with the following Hardware:

Hardware Setup:

Dell PowerEdge 2650
1 Dual Channel RAID Controller
1 Adaptec 3960D Ultra160 SCSI adapter (onBoard, not used)
1 Dual Channel Adaptec aic7899 Ultra160 SCSI adapter (used for extarnal Tape-Backup)

Kernel Version:
2.6.8.1

Problems:
The Kernel Panics appear if you try to use the external tape, but also randomly in time. There were also Panics with a less output than the posted one.

Temporary Solution:
If we don't load the aic7xxx kernel module, the server run stable.

The panics also appear with Kernel 2.6.9 and if we deactivated the unused onboard SCSI-Controller.

Does anyone else know a solution or has seen problems like this?

Thanks a lot for help.
