dmesg log

Sometimes I have errors like "GPU lockup CP stall for more than 10000msec", you can find dmesg output in the attached file. I'm already have drm.debug=15, dmesg output for 10 sec prior to debug will be in the following comment (I already have a plenty of those). This has happened since I have this system, so cannot bisect.
Really don't know what additional info is needed in such cases, please ask if anything else is needed for investigation/fix.

Is there some app that triggers this?

Unfortunately, no. Just happens suddenly.

Lockups are gone after one of the mesa/kernel updates.
