           Summary: kernel oops in 2.6.33 rc5 when dri is set to off in

dmesg with dri off and booting to X

If option dri is set to off and I'm booting to X then I get the oops. When it
is set to on (or I boot only to console) I do not get the oops. Still the
acceleration is not working when dri is set to on. It complains about dri
version mismatch which is strange since I compiled libdrm with
--enable-radeon-experimental-api and I recompiled xf86-video-ati and mesa only
after the new libdrm was installed. But this is probably a separate issue.
Anyway looks to me it should not be possible to make kernel oops so here is the
report. Ach, and it is an agp system but I never had any stability problems
with it on windows (also worked very well with 2.6.30 and agd5f's r6xx-r7xx-3d
drm module with agp 8x and even the fast writes).

I'll attach dmesg with the oops and also without it (a boot to console).
