dmesg logged via netconsole
When I try to use UVD on my laptop Dell Studio XPS 1645 with RV730 chip (Mobility Radeon HD 4670), the GPU hangs and is unable to work correctly. Virtual console switch works, and I even can restart X, but after that the picture is totally corrupt. I also tried to unload radeon by 'echo 0 > /sys/class/vtconsole/vtcon1/bind; rmmod radeon' and got kernel oops.
The log is attached.
The bug also reproduces on 3.13 from ubuntu-kernel PPA.
