I'm using the stock Debian kernel-image-2.6.10-1-686, that has:
CONFIG_X86_MCE=y
CONFIG_X86_MCE_NONFATAL=m
CONFIG_X86_MCE_P4THERMAL=y
hardware is a P4M Centrino. However, the device doesn't show up.
Indeed, if it works only on x86-64 and P4 w/EM64T, please add a note to
that to the the package long description, so that users of different
systems know they don't need this package. Something such as:
---------------------------
Description: Machine Check Exceptions collector and decoder
Starting with version 2.6.4, the Linux kernel no longer decodes and logs
Machine Check Exception events to the kernel log on its own.
.
Instead, the MCE data is kept in a buffer which can be read from userpace via
the /dev/mcelog device node.
.
You need this tool to collect and decode those events; it will log the decoded
MCE events into /var/log/mcelog. Currently, mcelog can decode MCE from AMD K8
and Intel P4 (including Xeon) processors.
.
Note that the MCE device only exists on x86-64 and P4 with EM64T, so
this package is not useful on different architectures.

Ciao,
Enrico
