Thanks to David Wolfskill for talking me through setting up a serial console, I'm able to extract some debugging information from my system now. Some initial bits (retyped by me, hopefully not too many mistakes) follow: kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0x48 fault code = supervisor read, page not present instruction pointer = 0x8:0xffffffff802b14fa stack pointer = 0x10:0xffffffffa263b9d0 frame pointer = 0x10:0xffffffffa263ba10 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = resume, IOPL = 0 current process = 38 (syncer) [thread pid 38 tid 100042 ] Stopped at propagate_priority+0x6a movq 0x48(%r15),%rbx Tracing pid 38 tid 100042 td 0xffffff003db4a000 propagate_priority() at propagate_priority+0x6a turnstile_wait() at turnstile_wait+0x20e _mtx_lock_sleep() at _mtx_lock_sleep+0x89 vfs_busy_pages() at vfs_busy_pages+0xd4 bufwrite() at burwrite+0x7b vfs_bio_awrite() at vfs_bio_awrite+0x5a vop_stdfsync() at vop_stdfsync+0x28c VOP_FSYNC_APV() at VOP_FSYNC+APV+0x3d sched_sync() at sched_sync+0x415 fork_exit() at fork_exit+0x86 form_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffffffa263bd40, rbp = 0 --- Is there anything else that might be useful in tracking down this problem? If it's anything that's very involved I may need to be pointed at an instruction manual! Cheers, Chris.
