Running Linux 2.6.37, I am getting these errors on one of a box:
[696782.810387] [Hardware Error]: No human readable MCE decoding support
on this CPU type.
[696782.810470] [Hardware Error]: Run the message through 'mcelog
--ascii' to decode.
[696783.585853] [Hardware Error]: No human readable MCE decoding support
on this CPU type.
[696783.585937] [Hardware Error]: Run the message through 'mcelog
--ascii' to decode.
Except that it never tells me the actual non-human readable form.
The error starts to show after 6-48 hours after a reboot (including
warm reboots). A second machine of the exact same configuration shows no
problems over the past 30 days. Environmental sensors of the problem box
show normal parameters.
How would I get the messages to run through mcelog?

It looks like a kind of corrected error.
Let's try the latest mcelog:
git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git

mcelog logs them. The kernel shouldn't be spewing these messages
at all, especially not for corrected errors (this is a still
unfixed regression for Intel CPUs)
Here's an older fix:
http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=6e3c7411d2b86bff210c59caa432e8e862037bfd

They are already logged, no need to do anything further.
