When starting a Firefox compilation job earlier today, my system locked up; ctrl-alt-f1 had no effect, etc. (I was able to restart with the REISUB technique.)
I'm on 64-bit Ubuntu Zesty, and I was running a kernel version that's currently in zesty-proposed to have the fix for https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674838 .
"uname -a" output:
Linux olive 4.10.0-22-generic #24-Ubuntu SMP Mon May 22 17:43:20 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Here's the relevant snippet from kern.log when the hang happened:
