Since I’ve started using my RV730 (HD4670) card and the r600 driver with it I
am frequently experiencing sudden slowdowns in window handling. Both window
switching as well as resizing becomes really laggy and so far I had to resort
to restarting my system to circumvent this. Here’s an example from dmesg as
soon as this happens:

Even the latest Git master I was pointed at in IRC did not yield any
difference. I have also tried pci=noacpi but except of different IRQ numbering
nothing did change. Please let me know what kind of other information you need.
