mcelog
------
In Linux 2.6.31+ the i386 kernel needs to run the mcelog utility
as a regular cronjob similar to the x86-64 kernel to process and log
machine check events when CONFIG_X86_NEW_MCE is enabled. Machine check
events are errors reported by the CPU. Processing them is strongly encouraged.
All x86-64 kernels since 2.6.4 require the mcelog utility to
process machine checks.
On x86 kernels the mcelog utility is needed to process and log machine check
events when CONFIG_X86_MCE is enabled. Machine check events are errors reported
by the CPU. Processing them is strongly encouraged.

These days most developers use `git send-email` instead of regular

If you are new to git then send your first patch to yourself. Save it
