Summary: Hard lock in DRM
(29598e5253ff5c085ccf63580fd24b84db848424 is first bad
commit)
Product: DRI
Version: XOrg CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P2
Component: DRM modules
AssignedTo: [email protected]

Commit 29598e5253ff5c085ccf63580fd24b84db848424 causes a hard lock when a GL
program is finishing, including glxinfo and glxgears. The program causes a hard
lock somewhere in the DRM clean up code, just before it would normally
terminate. I'm using GNU/Linux (kernel 2.6.18-rc7) with DRM and libdrm from the
Freedesktop Git repository, and Mesa3d from CVS. Hardware is x86_64 and r300.
Here is the git bisect log, which might be reformatted slightly by Bugzilla:

Add support for tracking drawable information to core
Actually make the existing ioctls for adding and removing drawables do
something useful, and add another ioctl for the X server to update drawable
information. The only kind of drawable information tracked so far is
cliprects.
