Both machines were running without problems for about 250 days and suddenly almost at same time, both of them crashed. both machines were running 2.6.32.21 (SMP x86_64) and using dahdi_dummy (dahdi-2.3.0.1) here's the tail of the backtrace: [] pollwake+0x57/0x60 [] ? default_wake_function+0x0/0x10 [] __wake_up_common+0x5a/0x90 [] __wake_up+0x43/0x70 [] process_masterspan+0x643/0x670 [dahdi] [] coretimer_func+0x135/0x1d0 [dahdi] [] run_timer_softirq+0x15d/0x320 [] ? coretimer_func+0x0/0x1d0 [dahdi] [] __do_softirq+0xcc/0x220 [] call_softirq+0x1c/0x30 [] do_softirq+0x4a/0x80 [] irq_exit+0x87/0x90 [] do_IRQ+0x77/0xf0 [] ret_from_intr+0x0/Oxa [] ? acpi_idle_enter_bm+0x273/0x2a1 [processor] [] ? acpi_idle_enter_bm+0x269/0x2a1 [processor] [] ? cpuidle_idle_call+0xa5/0x150 [] ? cpu_idle+0x4f/0x90 [] ? rest_init+0x75/0x80 [] ? start_kernel+0x2ef/0x390 [] ? x86_64_start_reservations+0x81/0xc0 [] ? x86_64_start_kernel+0xd6/0x100 Sorry, it's trimmed a bit :( I can't find any related bugreport, so I'm not sure whether I've hit some problem already solved. To me, it seems like some counter might have overflowed or the like (that could explain why machines were running for so long and then suddenly both of them crashed..) Of course used dahdi version was quite old, so I should update anyways, but I'd sleep safer if I'd know the problem already got fixed.. Anyone has some idea? Should more information be needed, I'd be more then glad to help... Thanks a lot in advance! with best regards nik -- ------------------------------------- Ing.
