Summary: Upgrading to current DRM modules git tree breaks i945GM
Product: Mesa
Version: CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i915
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
After an update from kernel 2.6.25 with DRM modules from a 2008/04/18 git
checkout to kernel 2.6.25.1 with DRM modules from today's git, applications
using DRI fail on startup, saying
DRM_I915_EXECBUFFER: -22
Userland is today's git xserver and mesa and xf86-video-intel-2.3.0. The same
userland works well when booting into the old kernel.
With the new kernel:
$ LIBGL_DEBUG=verbose etracer
[...]
