Here's what was on the console on the 2nd to last lock-up: kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 03 fault virtual address = 0x150 fault code = supervisor read, page not present instruction pointer = 0x20: 0xc0642e6e stack pointer = 0x28: 0xe4fd9b8c frame pointer = 0x28: 0xe4fd9bb0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 49 (swi4: clock sio) I've also seen hard locks with gkrellmd, fsck running in multi-user mode. -- Regards, Doug
