Bug Description
It appears Core i5-5300U (5th generation) Intel processor support is missing from Ubuntu 14 LTS. Also see the FAQ item for the error message "only decoding architectural errors" at http://
I'm guessing 6th gens are missing support. I'm also guessing the latest AMDs lack support.

Description: x86 Machine Check Exceptions collector and decoder
The Linux kernel for x86 CPUs no longer decodes and logs recoverable
Machine Check Exception (MCE) events to the kernel log on its own.
.
Instead, the MCE data is kept in a buffer which can be read from userspace
via the /dev/mcelog device node.
.
You need this tool to collect and decode those events; it will log the decoded
MCE events to syslog.
