Bug Description
[Impact]
Severe GPU lockup affecting the i915/i945 family of Intel chips, resulting in unrecoverable freeze of graphics, black screen and/or corruption, requiring a hard reboot to reset. The issue is widespread amongst these cards as evidenced by the large number of dupes; the hardware is common. Most users report this is a regression in behavior from maverick.
[Background]
Subsequent to the code included in maverick, upstream introduced an optimization to relax fencing on Intel hardware. This change reduced the amount of memory allocated for video buffers. However on older (pre-G33) hardware such as i915/i945 this results in increased chances of GPU lockups.
[Fix for Development Version]
Upstream has opted to disable the relaxed fencing optimization for their driver release, and the change is still present in their active upstream git tree. Thus, we will be pulling this fix when we update X in oneiric.
[Fix for Stable Version]
For natty, the attached patch is a backport of the patch that went upstream. This patch makes relaxed fencing into an xorg.conf option that can be set, and makes it disabled by default for gen < 33 chipsets.
[Steps to Reproduce]
The freezes typically occur intermittently after some period of use. For some people it occurs right at boot, others after minutes or hours of usage. Some users find that certain activities such as web browsing makes the issue more likely to occur, but others do not find it correlated to any particular action.
However, in all cases once the system is frozen, the file /sys/kernel/
With this patch applied, gpu freezes should either go away entirely, or become much less frequent. Freezes which still occur but have IPEHR values outside these two ranges may be unrelated bugs.
[Regression Potential]
The patch itself is relatively small and unlikely to introduce regression.
However, this switches optimization paths within the driver. It restores us to an older codepath so presumably this will at least be as stable as maverick, however the amount of testing this path has received on natty is limited. The code is upstream and being tested by the wider community and so far has not proven problematic.
Because it is disabling an optimization, it is possible some users of older hardware may see performance regress, but should be no worse than what was available in maverick.
[Original Report]
As instructed by Bryce I installed the following kernel on my Asus eee pc 701 running natty:
" Please test with the following kernel:
http://
by doing sudo dpkg -i linux-image....deb
Then I ran update manager.
After rebooting I browsed with google chrome. The system froze after 5 minutes.
I rebooted the same kernel and immediately got this problem popup. In addition there is font corruption - part of the letter t is missing in the browser.
