Thx for the new Kernel AceLan! I tested the x86_64 version on two different Boards. It got a little better I think - bug happens not that frequently imho. But still, if I e.g. press alt-f2 in Unity and start typing I still get lags and dmesg shows:
[ 85.166147] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 39358, at 39358], missed IRQ?

It's better reproducible if you play some opengl game. e.g. neverball. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761065 Title: [Sandybridge] Spurious "*ERROR* Hangcheck timer elapsed... blt ring idle" messages in dmesg when using compiz -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
