Your debug kernel 2.6.38-3-generic #30lp714719v201102101355 did freeze once before I had ssh set up. It did not freeze again but dmesg indicates a hang:
3023.928039] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 3023.930371] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 370145 at 370143, next 370146) [ 3023.930571] [drm:i915_reset] *ERROR* Failed to reset chip. There doesn't seem to be a lot of extra debug info in dmesg beyond what is in /var/log/kern.log? When I run 2.6.38-4 the system freezes within a few minutes and I get a similar dmesg: 1312.444041] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 1312.446392] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 108991 at 108989, next 108992) [ 1312.446597] [drm:i915_reset] *ERROR* Failed to reset chip. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/720468 Title: [i915gm] GPU lockup 554e2b4b (ESR: 0x00000001 IPEHR: 0x7f9c002d) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
