Summary: [KMS] Radeon kernel oops (null pointer dereference) radeon_atom_encoder_mode_set Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: tdro...@gmx.de Created an attachment (id=30172) --> (http://bugs.freedesktop.org/attachment.cgi?id=30172) /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) IP: [<f8cb74ba>] radeon_atom_encoder_mode_set+0x26a/0x950 [radeon] *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP last sysfs file: /sys/devices/platform/radeon_cp.0/firmware/radeon_cp.0/loading -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ Come build with us!
