Hello,
at Opteron-based x86_64 system sometimes I get message
Machine check events logged
(non-fatal). How can I read the correspondent events? From the source
code (arch/x86_64/kernel/mce.c) it sounds like some misc device with
MISC_MCELOG_MINOR 227 is registered (with name "mcelog"?), but there is
no such device under /dev.
Thank you.

Read the help
config X86_MCE
bool "Machine check support" if EMBEDDED
default y
help
Include a machine check error handler to report hardware errors.
This version will require the mcelog utility to decode some
machine check error logs. See

Your distribution is broken then. In fact it is supposed to run
mcelog regularly from a cronjob to log machine check events into
a disk log. Complain to them.
