vmexit's can cause the AMX registers to "misbehave" which can break
ZFS, even though ZFS doesn't use AMX at all.
This causes crashes and processes hanging forever in uninterruptible
sleep (the infamous D state) on Intel Xeon 4th gen HW, possible other
HW too, but we only got reports on Sapphire Rapids models.
