Hi there, I've just joined the bumpy road of -current, in order to answer a qustion about USB attached drives (see -stable and -fs), and am now learning about reporting lock order reversals. Here's my first, from the last dmesg.boot. Doesn't seem to be in the lor database or PRs. I'm running -current on amd64: FreeBSD duncan.reilly.home 9.0-CURRENT FreeBSD 9.0-CURRENT #0: Mon Oct 26 20:19:29 EST 2009 root_at_duncan.reilly.home:/usr/obj/usr/src/sys/DUNCAN amd64 lock order reversal: (sleepable after non-sleepable) 1st 0xffffff0002cc30a8 rtentry (rtentry) _at_ /usr/src/sys/net/route.c:1474 2nd 0xffffffff80e00b00 ifnet_sx (ifnet_sx) _at_ /usr/src/sys/netinet/sctp_bsd_addr.c:212 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2a _witness_debugger() at _witness_debugger+0x2e witness_checkorder() at witness_checkorder+0x81e _sx_slock() at _sx_slock+0x55 sctp_init_ifns_for_vrf() at sctp_init_ifns_for_vrf+0x2e sctp_addr_change() at sctp_addr_change+0xce rt_newaddrmsg() at rt_newaddrmsg+0x54 rtinit() at rtinit+0x358 in_ifinit() at in_ifinit+0x2fd in_control() at in_control+0x1047 ifioctl() at ifioctl+0xfc1 kern_ioctl() at kern_ioctl+0xc5 ioctl() at ioctl+0xfd syscall() at syscall+0x1af Xfast_syscall() at Xfast_syscall+0xe1 --- syscall (54, FreeBSD ELF64, ioctl), rip = 0x800b8084c, rsp = 0x7fffffffe4e8, rbp = 0x7fffffffef6a ---Received on Wed Oct 28 2009 - 04:13:33 UTC
