Hi people, I've three machines - FreeBSD 9.1 (i386+amd64) - at reboot usually the kernel dump and therefore gmirror rebuilds, etc. After reboot - kldload show the module is inserted but /dev/ipmi* is not populated, kldunload + kldload of the module fixes the access + /dev/ipmi* population. Any ideas (except upgrade which I plan to 9.3 soon)? +Waiting (max 60 seconds) for system process `vnlru' to stop...done +Waiting (max 60 seconds) for system process `bufdaemon' to stop...done + +Waiting (max 60 seconds) for system process `syncer' to stop...Syncing disks, vnodes remaining...9 Sleeping thread (tid 100093, pid 16) owns a non-sleepable lock +KDB: stack backtrace of thread 100093: +#0 0xffffffff808f3196 at mi_switch+0x186 +#1 0xffffffff8092bfa2 at sleepq_wait+0x42 +#2 0xffffffff808f3926 at _sleep+0x376 +#3 0xffffffff81551227 at ipmi_submit_driver_request+0x97 +#4 0xffffffff815519df at ipmi_set_watchdog+0xaf +#5 0xffffffff81551c8f at ipmi_wd_event+0x8f +#6 0xffffffff807bbdef at kern_do_pat+0x9f +#7 0xffffffff80984187 at sched_sync+0x1e7 +#8 0xffffffff808bbe3f at fork_exit+0x11f +#9 0xffffffff80bc3d9e at fork_trampoline+0xe +panic: sleeping thread +cpuid = 0 +KDB: stack backtrace: +#0 0xffffffff80920cf6 at kdb_backtrace+0x66 +#1 0xffffffff808ead0e at panic+0x1ce +#2 0xffffffff8092f172 at propagate_priority+0x1d2 +#3 0xffffffff8092fe9e at turnstile_wait+0x1be +#4 0xffffffff808d9198 at _mtx_lock_sleep+0xd8 +#5 0xffffffff8097d9b3 at vn_syncer_add_to_worklist+0x143 +#6 0xffffffff80981ac4 at reassignbuf+0xe4 +#8 0xffffffff8096a232 at bdwrite+0x52 +#7 0xffffffff809661c2 at bdirty+0x42 +#9 0xffffffff80af4ba9 at ffs_freefile+0x269 +#10 0xffffffff80b09711 at handle_workitem_freefile+0x101 +#11 0xffffffff80b09ba7 at process_worklist_item+0x377 +#12 0xffffffff80b0d8d6 at softdep_process_worklist+0x96 +#13 0xffffffff80b0fee7 at softdep_flush+0x197 +#14 0xffffffff808bbe3f at fork_exit+0x11f
