Hello,
I've hit a Kernel BUG with the combination of nonstandart kernel
modules. So dear linux-kernel readers, this bug report may or may not
apply to the standart kernel. But if you have any comments, please CC
me.
We use the dolphinics psb66 clustering card and a GForce 256 graphics
card.
We are not able to load both kernel the NVDriver (0.9-6) and the pcisci
- (DIS-Feb-07) together.
The second one loaded always hits a kernel bug in ioremap stating the
page already exists.
The Oops reports and the machine info follow.
Thanks for your time
Gert
