Here's some information about another slightly different lockup. CPU0 is blocked in smp_targeted_tlb_shootdown (vector 0xf5). CPU2 & 3 are in acpi_cpu_c1. CPU1 (again) is in acpi_cpu_c1, but it has an interrupt pending. In this case, the pending interrupt is bit 27. 224 + 27 = 251 = IPI_HARDCLOCK. How can I figure out how CPU1 got stuck in this state? As far as I can tell, there is either a h/w problem, or CPU1 has gone to sleep after starting to handle an interrupt.
