Sorry for spaming.. Ok. Last try:
I'm using vgaswitcheroo on T500 (Radeon/i915) and after upgrading kernel to
2.6.38 OOPS started to occur. Previously (2.6.37) everything worked fine. I
checked 2.6.39 and error still occurs.
Also when I add radeon.modeset=0 i915.modeset=1 to kernel command line
vgaswitcheroo is off and both cards are working OK.
This is exact error:
