How do you know this happened twice if you couldn't see any message?

Also, can you enable netconsole or serial console, if possible, and try
to catch full dmesg from the boot and up until it happens.

Also, catch the dmesg of the box on the next time it reboots after the
freeze (btw, try doing a warm reboot because this is the only way we can
preserve valid error information) - if all works ok, it should decode
the MCE before the freeze (if the MCE caused it and it actually is the
reason for the freeze).

This is needed because we want those errors to actually be seen.

Thanks.
