           Summary: d-r-t crashes at radeon_bo_unref()
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: aidan@cisco.com


latest d-r-t pull (that had pm3 merged) crashes often in the last few hours on
my rv790 with the same backtrace, doesn't seem to last more than 30 mins uptime
doing normal boring desktop tasks. this is with dynpm=1.  will try without
dynpm.

I've just had one of these crashes - same trace, current drt, RV670 AGP 32 bit
system after about 15 minutes of openarena with dynpm on.

Will see if I can get one with it disabled.

(In reply to comment #4)
I can't (so far) crash with today's d-r-t.

Could just be luck I suppose, but it only took 20 mins of openarena to get two
yesterday and I've just gone 50 mins OK.

yes the crash appears gone thank you, however I am seeing a new issue after the
pull.  every now and again there is screen flicker.  it is extremely fast, if
you blink you will miss it.  one time i noticed momentary display of garbage.

This happens when the reclocking misses the vblank period.  work is ongoing to
avoid that.

Created an attachment (id=35386)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=35386)
my .config

May be this bug is config-dependent, i was unable to run into  any crash  with 
attached .config (note various  debug options enabled). Currently i turn them
off one after another ....

May be  we should edit bug description, if crash was not only with dynpm=1?
Or should i open new bug, because my issue has nothing in common with dynpm
bugs (apart from being oops)?

Closing this bug as it seems original issue is now fixed. Andrew Randrianasulu
please open a new bug with a stripped log for your oops and attach there your
config and hw information, thanks.
