Comment 8 for bug 1674838

This problem made my system mostly unuseable since upgreading to zesty (4.10.0-19). One crash every 1-4 Hours.
Some workloads tend to trigger it faster (firefox + youtube) but the crash is unavoidable.
Desktop usage becomes completely impossible.
Normally i can sill ssh in, but only certain things work:
- top works fine, I always see one kernel thread hogging cpu. Sometimes additionally a userspace process (mostly firefox). htop hangs on exit.
- kill -9 on cpu hogging userspace process does not work - this seems weird
- trying to reboot gracefully hangs. SysRq works.

I just switched to 4.11-rc7 mainline, but its too soon to make any conclusions. I will report tomorrow.

Looking through the clones of this bug this seems to happen with quite different hardware.
My affected system is AMD x370 chipset with RyZen 7 1700X cpu.
The system was perfectly stable with yakkety (kernel 4.8.0-??)
