I think you misread what he was saying. :-) He's saying that his
system locks up hard after the kernel prints the "SMP: AP CPU #x
I believe this is the 2nd or 3rd report we've had of this behaviour, re:
system locking up hard after those messages. I'll see if I can find the
past reports; I'm going off of memory, but they were in recent days.
Also (for you Edwin), be aware of the security issues when enabling HTT,
as well as the possible decrease in system performance (while increase
in power draw) it can cause:
