Description of problem:
mcelog should be run much more frequently than daily.

machine checks are usually signs of extreme hardware badness and imminent doom.

running mcelog daily pretty much guarantees your /var/log/mcelog will be empty
as the machine will have crashed long before mcelog ever had a chance to run
(from direct experience, on x86_64).

i would recommend hourly at a _minimum_.

Additional info:
ideally, mcelog should sit with /dev/mcelog open and decode the machine checks
as they come in.
