This is with linux 2.6.37 from xorg-edgers.
If I do
echo dynpm > /sys/class/drm/card0/device/power_method
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.
Do you still have this issue ?
Yes, still happens with 2.6.38-020638rc4-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Any reason that it should be gone?
Confirmed with rv710.
This seems to be fixed with 3.2!
