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?
