Comment 79 for bug 1700373

I have now killed my 4-simultaneous compilation loop tests after 20 hours. With the previous microcode, 2 of 3 loop threads died with a segfault within 1 hour, so I consider this fixed.

@Others, Has anyone tested this with skylake/kabylake on zesty?
I have installed and boot tested using Ivy-bridge on zesty, but I'd feel slightly better if someone could test Sky/Kaby on zesty explicitly. Bonus points if you recreate the crash scenario, and verify resolution.

I don't think we need any more positive tests on X, please only report errors or failures going forward for X.
