Public bug reported:

I just rebuilt my home server with new hardware, and installed the
latest Debian 8.2 fresh Friday night.  Yesterday, a general protection
fault occurred while I was running mkvmerge.  I ran mkvmerge several
times before and after this incident, and was unable to reproduce the
problem.  My software raid array was resyncing when this occurred.

dmesg, lspci -nn, and lspci -v output attached (concatenated into one
file).
