Thanks for the link. But what kind of bug this could be? And could it be worked around? How can i help?

No. Windows-es didn't report any errors. The machine just broke someday when Windows 8 booted. Different Linux kernels fail with the same MCE. The same MCE rises sometimes (frequently, but not always) when i'm trying to write something to /sys entry for keyboard backlight or to rfkill bluetooth phy.

Are there any info on how to decode this MCE code? It is not covered in Intel's manuals. Hard to reason without any knowledge.
