Hi all,
Got this oops recently:

I know very little about the kernel, so I was hoping someone could help
me to track down the problem.
Kernel version is 2.2.17pre16, with reiserfs-3.5.23 patch applied. Also
have the DAC960 driver installed (using a DAC1164P card).
bonnie++ was running at the time, on a reiserfs partition on top of a
RAID 0+1 set. After the oops happened, I was unable to use or unmount
the partition (a reboot was required).
I'm not bothered if noone can offer a solution, but I do need to know
which part of the kernel actually has a problem, and how likely it is
that this problem will be fixed (I'm evaluating this machine, so if
this is going to be a recurring problem I need to know now).
If you need any more information, please let me know.
Regards,
Rob.
