Kernel from 19th Dec. Laptop suspended itself (for no reason), and upon resume got this: (again, laptop could not manage to do the dump, so this is hand transcribed) wakeup from sleeping state (slept 00:02:53) ata0: resetting devices .. done ata1: resetting devices .. done Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01fb093 stack pointer = 0x10:0xc874db48 frame pointer = 0x10:0xc874db68 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 13 (swi6: tty:sio clock) Stopped at _mtx_lock_flags + 0x43 cmpl $0xc03d16a0, 0(ebx) _mtx_lock_flags() at _mtx_lock_flags+0x43 mixer_reinit() at ds_ps_resume() bus_generic_resume() bus_generic_resume() bus_generic_resume() bus_generic_resume() bus_generic_resume() apm_resume() apm_processevent() apm_do_suspend() apm_timeout() softclock() ithread_loop() fork_exit() fork_trampoline() _mtx_lock_flags+0x43 corresponds to the compare of the line KASSERT(m->mtx_object.lo_class == &lock_class_mtx_sleep, .... in kern_mutex.c. It looks like m == NULL. I can't get any more information sadly, again the machine hung while trying to reset ther ATA channel for the dump.
