I updated my "canary" machine to -current today and it's not a happy camper. Trying to run a buildworld on it I get the follwing reproducible panic: FreeBSD/amd64 (ni.freebsd.dk) (cuau0) login: lock order reversal: 1st 0xfffff8011641a9a0 ufs (ufs) @ /freebsd/head/sys/kern/vfs_lookup.c:518 2nd 0xfffffe00e7858790 bufwait (bufwait) @ /freebsd/head/sys/ufs/ffs/ffs_vnops .c:262 3rd 0xfffff800b40ad5f0 ufs (ufs) @ /freebsd/head/sys/kern/vfs_subr.c:2101 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe0111361da0 kdb_backtrace() at kdb_backtrace+0x39/frampanic: bad stray interrupt cpuid = 2 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe011120e9e0 kdb_backtrace() at kdb_backtrace+0x39/frame 0xfffffe011120ea90 vpanic() at vpanic+0x126/frame 0xfffffe011120ead0 kassert_panic() at kassert_panic+0x136/frame 0xfffffe011120eb40 intr_event_handle() at intr_event_handle+0x11d/frame 0xfffffe011120eb90 intr_execute_handlers() at intr_execute_handlers+0x48/frame 0xfffffe011120ebc0 lapic_handle_intr() at lapic_handle_intr+0x73/frame 0xfffffe011120ebf0 Xapic_isr1() at Xapic_isr1+0xa4/frame 0xfffffe011120ebf0 --- interrupt, rip = 0x11f7b11, rsp = 0x7fffffff8b50, rbp = 0x7fffffff8b80 --- KDB: enter: panic [ thread pid 72149 tid 100102 ] Stopped at kdb_enter+0x3e: movq $0,kdb_why db> -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
