Priority: medium
Bug ID: 66972
Assignee: dri-devel at lists.freedesktop.org
Summary: GPU lockup CP stall with radeon.dpm=1 on BARTS/6850
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: a.heider at gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: DRI CVS
Component: DRM/Radeon
Product: DRI
Using 3.11-rc1 with merged drm-fixes (d1ce3d5 uvesafb: Really allow mtrr being
0, as documented and warn()ed) on top.
There're no glaring problems without radeon.dpm=1, but with dpm I get this:

lightdm takes unusually long to show up due to the 1st stall. Eventually I can
log in (xfce without compositing), but just running dmesg in a fullscreen
terminal makes X crash (Backtrace is useless, let me know if one with debug
symbols helps).
