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.
