I expected to be able to copy data to disk connected to a Promise Technology, Inc. 80333 [SuperTrak EX8350/EX16350] without a kernel panic.

4:
When copying data to harddrives on Promise Technology, Inc. 80333 [SuperTrak EX8350/EX16350] the kernel panics after some time. It is not a determistic time, but it is reproducable.

A picture of the panic is attached

This seems like the same issues, unfortunatly without a solution:

http://kerneltrap.org/mailarchive/linux-scsi/2007/12/5/478940

I will try to do as described in the followups

[Kim Højgaard-Hansen (kimrhh)]

we did as instructed in the LKML post:

build the kernel as instructed in: https://help.ubuntu.com/community/Kernel/Compile
where we chose to build the flavor "server"

The result:

We are going to upgrade the machine to lucid in order to try to overcome this bug, so we will not be able to do any further testing for this from here on.

After the upgrade to 10.04 LTS the bug seems to have disappeared, at least we have not been able to reproduce it.
