Maciej W. Rozycki d4d25deca4 x86: fix NMI watchdog & 'stopped time' problem
More than 3 years ago Niclas Gustafsson reported a 'stopped time'
problem:

This may be because buggy SMM firmware messes with the 8259A (configured
for a transparent mode -- yes that rare "local-APIC-edge" mode is tricky
;-) ) insanely.

this should resolve:
