Avi, i expect more boxes to be affected by this bug, and the DMI
solution just does not scale.
So could we please disable VMX from the emergency-shutdown code
instead of twiddling with the reboot method?
Something like this might work as well: iff VMX is enabled, we just do
smp_send_stop() (instead of skipping it) which should take care of
this.
Ingo
