Public bug reported:
Hi, running 16.04 server on a Dell Poweredge T20. Since latest
meltdown/spectre Kernel update i get "mce: [Hardware Error]: Machine
check events logged" shown in the logs. This happens when the server is
compiling stuff scheduled per cron.
the mce-log shows entries like:
Hardware event. This is not a software error.
