Bug Description

My computer is Sony Vaio VPCCB2S1E with these GPUs:
Intel® HD Graphics 3000
AMD Radeon™ HD 6630M

I have fglrx drivers in my hybrid fglrx/intel system and I am using the integrated GPU, setup by:
amdconfig --px-igpu

The problem is that in every reboot after I have successfully used the iGPU, the X server to crashes, which means:
- One time the X server loads normally **
- One time the X server crashes, giving the error in the attached log and the only thing I can do is reboot the system
This periodic behaviour is totally reproducible: once it crashes, after the reboot it works fine, on the next reboot crashes again, and so on...

** I had to use the patched fglrx/intel drivers from:
https://launchpad.net/~andrikos/+archive/ppa
in order to avoid Bug #1068404

WORKAROUND: Run this command (as root) after every reboot:
aticonfig --del-pcs-key=DDX,PX_GPUDOWN

I post two logs, both of them crashes when I reboot after I have successfully used the iGPU.

Their difference is that the first one refers to the configuration where the iGPU is used again and it is the procedure described above.
The second one shows what happens if I select the dGPU before I reboot (running amdconfig --px-dgpu, while using the iGPU).

Do you still get the crash if you reboot after you get this error?

Yes, computer crashes every second time it boots. It seems like the command above did not change anything.
I've placed it in /etc/rc.local. Is that correct. Am I supposed to place it anywehere else or run mannually?

Nick Andrik (andrikos) wrote :

I have tried to run it manually. It needs it just once after each reboot.
You can automate it by putting in rc.local.

In any case, after you run it once, you will get the message you told
me, but you will not get the crash on the next reboot (at least this
is the behaviour in my computer)

Apparently with Catalyst 13.6 beta drivers (version 2:13.101-0ubuntu1) this bug is solved, could the other people experiencing this bug (except for Nick) confirm this?
