My system started crashing at regular intervals (10 minutes to one hour)
since this afternoon;
I'm not aware of running any updates, but I might have done an "aptitude
safe-upgrade" anywhere in the past week. I'm fully up to date on Ubuntu
14.04.3 now.
The problems seem to exclusively occur when running Chrome (47) /
Chromium (45) (I switched to that browser when the problem occurred a
few times, but this didn't solve it), but this may also simply be a
consequence of my browser being the most Graphics-heavy part of the
system.
I'm running on a MacbookPro, inside Parallels; this was not a problem
until this afternoon.
