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@kernel-bugs.osdl.org Reporter: madigens@gmail.com 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:
