It would be good to see what's at ffffffff81d58fad. My guess would be
that it's xsetbv.
If it is then you probably want to make sure you are running hypervisor
that has commit e8121c54 ("x86/xsave: enable support for new ISA
extensions"). Looks like the first version that has it is 4.5 and you
seem to be running 4.4.2.
Copying Jan to see if there are plans to backport this (probably not
since it's a new feature).
