From Yingying:

You can get details from patch description. Basically, on some machines (AFAIK, romley, Lenovo x220, Toshiba Z830 .etc. ) with buggy Bios, the firmware will generate quite lots of fake MCE error msg which confuses users and lead them to believe they are experiencing real hardware errors.

 The fix is included in the following upstream patch:
