PROBLEM: i915 regression between 2.6.39-rc6 and 2.6.39-rc7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

When running the 2.6.39-rc7, I've observed a problem on my laptop (DELL
XPS15) which uses the i915 driver. Frequently, when moving the mouse
over, the cursor does only trigger the modification on the desktop after
a few seconds (like icons
highligthing). When this occurs, the following message appear in the
kernel log at the moment when the waited action occurs:

[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 905, at 905], missed IRQ?

Switching back to 2.6.39-rc6 fixes the issue.

It runs gnome 3 which uses glx to add some effect. Maybe this is linked.
When using the simple twm window manager, the problem does not seem to
occur.
