https://bugzilla.kernel.org/show_bug.cgi?id=78661 Bug ID: 78661 Summary: GPU sometimes locks up after boot and/or resume Product: Drivers Version: 2.5 Kernel Version: 3.15.1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: madigens@xxxxxxxxx Regression: No I've been getting these hangs since at least 3.13.x on Ubuntu 14.04, but I remember getting them before that, too. It doesn't always happen, mostly the system works as usual. Sometimes though, I boot up or resume and upon opening an application or moving the mouse, I get a garbled screen, after a few seconds it goes back to normal, only to hang shortly thereafter again or hang completely. I can't remember this happening during normal use, meaning if it doesn't happen shortly after boot or resume, the system works fine. I cut some suspicious lines from syslog: Jun 22 10:31:40 nikolaus-desktop kernel: [ 86.067026] radeon 0000:01:00.0: ring 5 stalled for more than 81420msec Jun 22 10:31:40 nikolaus-desktop kernel: [ 86.067034] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000000000001 last fence id 0x0000000000000000 on ring 5) Jun 22 10:31:41 nikolaus-desktop kernel: [ 86.929541] radeon 0000:01:00.0: GPU reset succeeded, trying to resume Jun 22 10:31:41 nikolaus-desktop kernel: [ 86.986723] [drm] PCIE gen 2 link speeds already enabled Jun 22 10:31:41 nikolaus-desktop kernel: [ 86.988854] [drm] PCIE GART of 1024M enabled (table at 0x000000000025D000).
