--- Comment #36 from Petteri Aimonen (j...@kernelbug.mail.kapsi.fi) ---
@krakopo The 00000020 MXCSR value is also exactly like it was for me before the
bug fix. So something is definitely clearing MXCSR after it should be set to
0x1F80 by kernel_fpu_begin().

Can you disassemble kernel_fpu_begin() to verify that the ldmxcsr instruction
is present close to its end? Also, check that /proc/cpuinfo flags has "sse" in
it - not sure though how that could possibly be missing.
