          Assignee: xorg-driver-ati at lists.x.org
           Summary: Panic(?) after 10-20 minutes use of R7 265 in X
        QA Contact: xorg-team at lists.x.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: org.freedesktop at io7m.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: Driver/Radeon
           Product: xorg

I'm experiencing a strange crash that causes the machine to reboot after 10-20
minutes of use in Xorg. The crash does not appear to require any use of OpenGL
(simply using a browser for that time on an xfce desktop will trigger it).
There are no useful error messages logged in dmesg before the crash happens.
When the crash occurs, the screen is quickly replaced with garbage, flickers,
and then the machine reboots a few seconds later (presumably there is a panic
message on the console, but I cannot see it with X in the way).

The card is an R7 265. Specifically, this one:


The card is only a week old, and the machine has been using a 6570 for a few
years and has been completely stable.

I've performed the usual troubleshooting (have run memtest to eliminate
problems with RAM, have kept a careful eye on temperature sensors to eliminate
thermal issues - the machine is well ventilated and in a well ventilated area).
I can't completely eliminate the power supply yet but I am reasonably confident
that it's not broken (it's a good quality Seasonic PSU). I'll be obtaining
another power supply today to eliminate that.

The operating system is Arch Linux on x86-64. Please see attached dmesg and
xorg logs.

I'm not sure what other information I can provide (or if there's a reliable
means of getting panic information from the machine), please advise!
