Hi,
Thanks for reporting it. Am I correct in assuming v3.3 from experimental behaves the same way?
Yes, the bug is still present with that kernel.
If so, please report this upstream to<http://bugs.freedesktop.org/>, product DRI, component DRM/Radeon, and let us know the bug number so we can track it.
Now reported upstream, with attached logs, as Bug 48422. Mike
