I see both CPUs did interrupt handling again. Maybe it's a real locking problem. Here are some more suggestions for testing (if you don't find anything better): - try without SMP, so: 'acpi=off lapic nosmp' - lock debugging turned on as much as possible plus maybe for curiosity: - different CONFIG_HZ - 8139TOO_PIO = y ... > IRQ-problems with the Un-Interruptible-Power-Supply I wouldn't be surprised...
