Just had this lock order reversal on a late-november kernel. Haven't seen it mentioned before. Dec 16 19:07:15 epsilon kernel: rl0: promiscuous mode enabled Dec 16 19:07:15 epsilon kernel: lock order reversal Dec 16 19:07:15 epsilon kernel: 1st 0xc0429cc0 bpf global lock (bpf global lock) @ /usr/src/sys/net/bpf.c:375 Dec 16 19:07:15 epsilon kernel: 2nd 0xc296b9c4 rl0 (network driver) @ /usr/src/sys/pci/if_rl.c:1753 Dec 16 19:07:15 epsilon kernel: rl0: promiscuous mode disabled Is there any way I can set my machine to drop to debugger on any lock order reversal _other_ than sound-related LOR's? I realise these reversals are not as useful without a traceback, but as I use thismachine for playing audio....
