[Bug 459961] Re: radeon_dma.c:210: radeonRefillCurrentDmaRegion: Assertion `dma_bo->bo->cref == 1' failed.

 

Similar problem here with Dell Inspiron 5100 and Google Earth.
I was going to file this under bug #459153 but since that was marked as duplicate of this one, I'll just leave it here. After this crash, the system becomes either completely unresponsive or pretty much unusable, and cannot even be shut down properly. celestia also causes the warning to appear but it does not hang the system. I do not see any problem with /usr/lib/xscreensaver/hyperspace though. Please let me know if any more information is needed.

We apologize for the inconvenience, but Google Earth has crashed.
