--- Comment #17 from Andrew W. Nosenko <andrew.w.nosenko at gmail dot com> 2012-10-03 17:32:51 UTC ---
Sorry, but commited patch does NOT fixes the problem.
It does just reverse -- disables AVX & Co on systems the has OSXSAVE,
XSTATE_SSE and XSTATE_YMM bits set, while the intention was to disable if any
of these bits are not set.

Proposed followup patch is attached.
