/var/log/messages drm-next modeset=1
My system is a Pentium4 (32bit) with a Radeon x850pro (AGP).
I tried the drm-next kernel (build date Wed Sep 16 09:14:34 CEST 2009), but
with radeon kms enabled I get an kernel oops:
drm-next (modeset=1) --> "/var/log/messages drm-next modeset=1" attachment
With kernel 2.6.31 (same config) it works:
2.6.31 (modeset=1) --> "/var/log/messages 2.6.31 modeset=1" attachment
I also tried booting the drm-next kernel with radeon.modeset=0, unload the
radeon module and load it with modeset=1. The result is also a working
environment but many artifacts:
drm-next (modeset=0) --> "/var/log/messages drm-next modeset=0" attachment
Error:
BUG: unable to handle kernel NULL pointer dereference at (null)
