While testing a fix for http://

I discovered that running my little test program made the machine
panic with a machine check error.
After restarting, /var/log/mcelog contained:
mcelog: failed to prefill DIMM database from DMI data
Kernel does not support page offline interface
mcelog: mcelog read: No such device

I will attach a png of the panic backtrace along with the test program.
