           Summary: Desktop freezes quickly every now and then with dynpm
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ernstp@gmail.com


This is with linux 2.6.37 from xorg-edgers.
If I do
echo dynpm > /sys/class/drm/card0/device/power_method
Run compiz
Grab a window and move it around, every now it freezes quickly and the resumes.
The mouse movement during that period is completely lost.
I'll try more kernels...

It also happens with the drm-next kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2010-11-10-maverick/
It does not happen with Ubuntu Mavericks default 2.6.35 kernel.

This is due to the pm code holding a number of locks while waiting to update
the clocks.

Yes, still happens with 2.6.38-020638rc4-generic from
http://kernel.ubuntu.com/~kernel-ppa/mainline/
Any reason that it should be gone?
