royger 35bdc8c699 geom: fix initialization order ... There's a race between the initialization of devsoftc.mtx (by devinit) and the creation of the geom worker thread g_run_events, which calls devctl_queue_data_f. Both of those are initialized at SI_SUB_DRIVERS and SI_ORDER_FIRST, which means the geom worked thread can be created before the mutex has been initialized, leading to the panic below: wpanic: mtx_lock() of spin mutex (null) @ /usr/home/osstest/build.135317.build-amd64-freebsd/freebsd/sys/kern/subr_bus.c:620 cpuid = 3 time = 1 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe003b968710 vpanic() at vpanic+0x19d/frame 0xfffffe003b968760 panic() at panic+0x43/frame 0xfffffe003b9687c0 __mtx_lock_flags() at __mtx_lock_flags+0x145/frame 0xfffffe003b968810 devctl_queue_data_f() at devctl_queue_data_f+0x6a/frame 0xfffffe003b968840 g_dev_taste() at g_dev_taste+0x463/frame 0xfffffe003b968a00 g_load_class() at g_load_class+0x1bc/frame 0xfffffe003b968a30 g_run_events() at g_run_events+0x197/frame 0xfffffe003b968a70 fork_exit() at fork_exit+0x84/frame 0xfffffe003b968ab0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe003b968ab0 --- trap 0, rip = 0, rsp = 0, rbp = 0 --- KDB: enter: panic [ thread pid 13 tid 100029 ] Stopped at kdb_enter+0x3b: movq $0,kdb_why Fix this by initializing geom at SI_ORDER_SECOND instead of SI_ORDER_FIRST.
