            Bug ID: 87992
           Summary: X crash because
                    si_restrict_performance_levels_before_switch(?)
           Product: xorg
           Version: 7.4 (2008.09)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Driver/Radeon
          Assignee: xorg-driver-ati at lists.x.org
          Reporter: oyvinds at everdot.org
        QA Contact: xorg-team at lists.x.org

Xorg crashed, dmesg had this message afterwards:

[191856.414365] [drm:si_dpm_set_power_state] *ERROR*
si_restrict_performance_levels_before_switch failed

total scandal.

Linux meilong 3.18.1-gentoo #1 SMP PREEMPT Fri Dec 26 12:45:10 CET 2014 x86_64
Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz GenuineIntel GNU/Linux

x11-drivers/xf86-video-ati 7.5.0
x11-libs/libdrm 2.4.58
media-libs/mesa 10.3.5
x11-base/xorg-server 1.16.2.901

I can not remember this happening with kernel 3.17.x. Crash happened after
about 2 days of uptime and it had been suspended to RAM a few times during that
period of time.

I was, so sorry, not running with options drm debug=0x06 at the time of this
unfortunate event so I will have to come back with additional information
if/when this happens again.

http://www.phoronix.com/scan.php?page=news_item&px=MTgzNzI  story is that 3.19
will have all sorts of fixes so this bug may not be that relevant, so sorry for
filing it if this is already fixed.

Please let me know if/how I can provide additional information.
