Within a few minutes of using 3.2-rc6, the screen flickered black and back exactly as it does when the problem occurs; it was then immediately followed by the full machine hang I saw with 3.2-rc5.
So, IMHO the problems possibly started with the GPU hang in 3.2-rc4-oneiric, turned into a full machine hang in 3.2-rc5-precise and morphed into the "X/GPU gets reinitialised (toavoid a hang?), but then the whole machine hangs anyway" issue of 3.2-rc6. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/968520 Title: i915 GPU hang with WARNING: at /build/buildd/linux-3.2.0/drivers/gpu/drm/i915/i915_drv.c:413 __gen6_gt_wait_for_fifo+0x94/0xa0 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/968520/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
