kernel messages

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

After lockup I see this message:

but similar message earlier did not cause lockup

Earlier versions of kernel+mesa would occasionally lock up displaying garbage
randomly at any time. I have not seen that for a while but the card still
occasionally locks up when running a 3D application. After lock up the card
keeps showing static screen of something the application rendered and movable
cursor. It *seems* to happen most often when there is some setup in progress
like loading a new scene.
