Starting with version 2.6.4, the Linux kernel for x86-64 no longer decodes and logs recoverable 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.
