dmesg_3.12-rc3.txt
Hello devs,
I use the Oibaf Updated and Optimized Open Graphics Drivers PPA on Ubuntu
Precise
with kernel 3.11 an 3.12-rc3.
After the update this monday my system is not usable anymore.
I made a new update today with no changes.
The system boot normaly to the kde desktop an then stop immediately to respond.
With luck, sometimes i can switch to console ctrl-alt-F1.
The dmesg output from the console is attached.
I try with and without radeon.dpm=1 , it doesn't make difference.
The GPU lockup every 10 seconds</pre>
