Ok, but what should the good and bad commits for the bisect be?
I had already done a bisection earlier and found that the commit adding and
enabling runtime power management was where the problems began.

Does disabling dpm help (radeon.dpm=0)? if not, any chance you could bisect?
Also, please attach your dmesg output with the latest patch applied.

Even with the latest patch applied

No, unfortunately GPU reset still occurs on startup, suspend, resume and
shutdown.
The laptop did suspend faster than earlier cases though, maybe the GPU was able
to break out of the reset cycle earlier.

Unfortunately, the problem still occurs even with the new patches. I applied
them against the latest source code of the kernel from git, after this commit:

Oops, typo in last comment. When I turn off the GPU using:

Turning off the dedicated GPU works fine, turning off the GPU doesn't.
The dedicated GPU is a Radeon HD 6650M . The kernel identifies it as a TURKS
GPU.
