Thank you, I ran a few tests and left karma. Something weird about the debug kernel: On a Phenom II system, after booting with the debug kernel and then rebooting with the regular one, I got only 1 core working. I had to power down and cold boot the regular kernel to get all six of them back. I tried it about a dozen times and it was always the same; does anyone have any ideas why this would happen? I don't know if I should be looking for something else, here's the system log from one of those boots, grep'd for CPU: Feb 03 16:08:52 kernel: smpboot: Allowing 8 CPUs, 7 hotplug CPUs Feb 03 16:08:52 kernel: setup_percpu: NR_CPUS:1024 nr_cpumask_bits:8 nr_cpu_ids:8 nr_node_ids:1 Feb 03 16:08:52 kernel: percpu: Embedded 36 pages/cpu @ffff97f6afc00000 s108888 r8192 d30376 u262144 Feb 03 16:08:52 kernel: pcpu-alloc: s108888 r8192 d30376 u262144 alloc=1*2097152 Feb 03 16:08:52 kernel: pcpu-alloc: [0] 0 1 2 3 4 5 6 7 Feb 03 16:08:52 kernel: SLUB: HWalign=64, Order=0-3, MinObjects=0, CPUs=8, Nodes=1 Feb 03 16:08:52 kernel: RCU restricting CPUs from NR_CPUS=1024 to nr_cpu_ids=8.
