The options I asked you to change were meant to eliminate any possible
source for high latencies in case of bug. You can return to a normal
configuration now: re-enable SMP or APIC if you prefer to remain in
single processor mode, disable the I-pipe tracer if you want to avoid
the overhead, and re-enable priority coupling if you prefer to use it.
