Ever since 2.1.131 I got oopses when running some scsi-intensive operations. I can reproduce this oops with deadly accuracy. A simple "dd if=/dev/scd2 of=/dev/null bs=2048" is enough to reproduce this oops. I even updated the BIOS of my AHA-2940UW from 1.21 to 1.34.3 without any succes. Attached you will find the output of ksymoops, and the contents of /proc/scsi/scsi and /proc/scsi/aic7xxx/0. If you need any further information just tell me.
Regards
Martin

Options used: -V (default)
-o /lib/modules/2.2.0/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
You did not tell me where to find symbol information. I will assume
that the log matches the kernel and modules that are running right now
and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
