First I checked /proc/cpuinfo which had 4790.8 as the value for bogomips
with noapic and nolapic in the grub2 config. I removed these options
and rebooted. This time I got 4791.43. So I'm guessing that if I lost
anything, it's not enough to matter. Am I right?
Thanks

If the bogomips of the single-core is 2x the bogo of the dual core,
then you’ve not lost anything – you are simply letting Linux control
the sharing of the CPU instead of the CPU.
(at least for the stupid hyperthreading stuff, all hyperthreading did
was give you two CPUs running at half the clock speed of the CPU…
Helped Windows users since Windows did such a bad job of time slicing
on a single CPU…)

*Subject:* fix lockup issue left with one core
So far this beast has behaved itself for 3 days. Today I handbrake on
a tv show episode I have on dvd. It's a 30 minute show and Handbrake
normally takes about 20 minutes to encode a 30 minute show. This time
I noticed the estimation of how long it would take hovered around 45
minutes. I then opened top and pressed 1 once it started. It showed
only cpu0. Shouldn't cpu1 also be there? I looked around online and
found that using the noapic option in grub only allows one core of a
multi core processor to run. Is there any way to enable apic and
lapic if necessary without it causing my machine to lock up again?
Thanks
