I have been updating all the while and rebooting, so hard to tell if something else got picked up, but I suspect the C6 disable did the trick. At some point, I might try enabling it back again, maybe after the 18.04 release.
At this point, not sure if you want to keep this bug open, whatever works for you guys.
I used Zenstates-Linux from Kai-Heng Feng's reference to https:/ /bugzilla. kernel. org/show_ bug.cgi? id=196683 and things have been much stabler, I don't think I have seen a freeze since then.
