Volker & Kris, Sorry for kind of hi-jacking your thread. Just hopefully we all can work together to fix this issue (if there is one). Out machine did goto in to a "hard lock". Nothing showed up on the screen or logs. I did see something from WITNESS in dmesg. See below. But this does not show up at the time of the crash. If I remember correctly this show up at boot time. We have added the following kernel options: options DDB options KDB options BREAK_TO_DEBUGGER options INVARIANTS options INVARIANTS_SUPPORT options WITNESS options DEBUG_VFS_LOCKS options DEBUG_MEMGUARD -dmesg------- softdep_waitidle: Failed to flush worklist for 0xc44ffcf8 em1: link state changed to DOWN bridge0: Ethernet address: 66:9e:c9:a6:f5:27 em0: promiscuous mode enabled em1: promiscuous mode enabled em1: link state changed to UP lock order reversal: 1st 0xc06e0820 polling (polling) @ /usr/src/sys/kern/kern_poll.c:422 2nd 0xc473070c if_bridge (if_bridge) @ /usr/src/sys/net/if_bridge.c:1976 KDB: stack backtrace: witness_checkorder(c473070c,9,c068bfbc,7b8) at witness_checkorder+0x55c _mtx_lock_flags(c473070c,0,c068bfbc,7b8,c473070c,...) at _mtx_lock_flags+0x41 bridge_input(c43d9000,c4740000,c43a828c,c43a8000,c4740000,...) at bridge_input+0x80 ether_input(c43d9000,c4740000,c43a828c,0,c0675f3c,...) at ether_input+0x122 e1000_rxeof(d43f2cbc,c0524e5d,d43f2ca8,1,5,...) at e1000_rxeof+0x19b e1000_poll(c43d9000,0,5) at e1000_poll+0x46 netisr_poll(0) at netisr_poll+0x70 swi_net(0,c4315438,c4323a80,c050a484,c4322648,...) at swi_net+0xb0 ithread_loop(c430f700,d43f2d38,c430f700,c050a484,0,...) at ithread_loop+0x1de fork_exit(c050a484,c430f700,d43f2d38) at fork_exit+0x7d fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xd43f2d6c, ebp = 0 --- softdep_waitidle: Failed to flush worklist for 0xc44ffcf8 em0: link state changed to UP ---------------- _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
