mcelog

mcelog decodes machine check events (hardware errors) on x86-64 machines running a 64-bit Linux kernel. It should be run regularly as a cron job on any x86-64 Linux system (if it is not in the default packages on your x86-64 distribution, please complain to your distributor). It can also decode machine check panic messages from console logs.
