            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:

Does booting with radeon.dpm=0 on the kernel command line in grub help?  Please
attach your full dmesg output.

Speaking of hangs, every once in a while I get lockups on boot where the screen
stays corrupted or black and even the reset button doesn't help and I have to
long-press the power button. Theres no log for those hangs so I don't know if
they're related to this bug. Anything I can do to further analyze these hangs?

Make sure you power off completely before testing the new patch rather than
just a warm reboot to make sure the old register state is not retained.

Okay :)

After a few days of use, I got my first corrupted screen this morning. I could
reisub though. Unfortunately, nothing in the logs... will keep testing.

New hangs on cold boot on 3.15.6

Alright, the lockups were few and far between on 3.15.5 with both patches, now
with 3.15.6 (installed from Ubuntu's mainline kernel repo) I always get a short
hang on the first boot in the morning. It continues but I have to reboot once
to avoid further short hangs and work normally. Log from first cold boot
attached.
