Ok, can you catch the whole dmesg when you boot the machine _after_ the
sudden poweroff? You can send it to me and Andreas (on CC) privately if
you prefer.

Important: make sure the kernel has CONFIG_X86_MCE and
CONFIG_EDAC_DECODE_MCE built-in.

Please make sure to use a recent kernel, i.e. 3.4, 3.5 is fine.

Thanks.
