It seems to be that kernel crashes because of i915 with random uptime and load
average.
The only way to boot and survive after hang is to use boot parameters
"i915.semaphores=1" and "i915.enable_ppgtt=0".
A (fast) way to reproduce bug:
1) open Google Chrome
2) go to video-streaming website (e.g. YouTube)
3) expand video in fullscreen
4) collapse to windowed mode
5) repeat steps 3 and 4 few times ()
Result: system stops responding (even Magic SysRq doesn't work) and last
seconds of sound are repeated at loop.
