Description Ari Entlich 2008-12-16 17:34:46 UTC

Running a drm-intel-next kernel, xf86-video-intel git master with KMS enabled, libdrm modesetting-gem, and server 1.5.99.3, the X server gets itself into an infinite loop and freezes up. The rest of the system is still functional.

These kernel messages may be related:

This happened while trying to run glxgears.

Comment 3 Gordon Jin 2009-02-03 18:49:45 UTC

Does this still exist with the current xf86-video-intel and libdrm master (don't use modesetting-gem branch)? 

Do you actually enable KMS in kernel? Please attach dmesg.

Feedback timeout. Please reopen if you could answer comment#3.

Mass version move, cvs -> git
