After updating to the official mesa-7.4-0ubuntu3 I got the freeze after about 4 hrs continuous use. Again, it happened during an alt-tab and was associated with a period of sluggish performance.
I pretty much already knew from prior testing that the fix wouldn't solve it for me, although I was surprised it lasted 4 hrs, usually it hit within 1 hour. One thing that is quite interesting to note is that the intel_gpu_dump output is completely different from both these two cases. ** Attachment added: "i915_debugfs_bwh2.tgz" http://launchpadlibrarian.net/25695454/i915_debugfs_bwh2.tgz -- [i965] X freezes starting on April 3rd https://bugs.launchpad.net/bugs/359392 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list universe-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/universe-bugs
