Issue #2047 has been updated by Chris Turner. Description updated Status changed from New to Closed This is pretty old & seemed to be crashing in threads/vfs which has changed significantly since then. I'm going to close, and if this occurs again, reopen. ---------------------------------------- Bug #2047: panic: lockmgr: pid -1, not exclusive lock holder thr 0xd7f53ed8/0xd7f545d8 unlocking http://bugs.dragonflybsd.org/issues/2047 Author: Chris Turner Status: Closed Priority: Normal Assignee: Category: Target version: From latest x86 / GENERIC_SMP when running a make installworld onto a vnd - crash in leaf:/home/cat/crash/installworld_vn.tar.gz Version String: DragonFly v2.9.1.1087.gcf014-DEVELOPMENT #3: Tue Apr 12 00:59:30 UTC 2011 [email protected]:/usr/obj/usr/src/sys/GENERIC_SM P _get_mycpu (di=0xc07d7300) at ./machine/thread.h:79 79 __asm ("movl %%fs:globaldata,%0" : "=r" (gd) : "m"(__mycpu__dummy)); (kgdb) #0 _get_mycpu (di=0xc07d7300) at ./machine/thread.h:79 #1 md_dumpsys (di=0xc07d7300) at /usr/src/sys/platform/pc32/i386/dump_machdep.c:264 #2 0xc03691d8 in dumpsys () at /usr/src/sys/kern/kern_shutdown.c:893 #3 0xc03697e5 in boot (howto=<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:388 #4 0xc0369a4a in panic ( fmt=0xc06cdec0 "lockmgr: pid %d, not %s thr %p/%p unlocking") at /usr/src/sys/kern/kern_shutdown.c:799 #5 0xc035b633 in lockmgr (lkp=0xc6a054a8, flags=6) at /usr/src/sys/kern/kern_lock.c:475 #6 0xc03b8da0 in BUF_UNLOCK (bp=0xc6a05290) at /usr/src/sys/sys/buf2.h:111 #7 brelse (bp=0xc6a05290) at /usr/src/sys/kern/vfs_bio.c:1677 #8 0xc03baddb in bpdone (bp=0xc6a05290, elseit=1) at /usr/src/sys/kern/vfs_bio.c:3845 #9 0xc03bb370 in biodone (bio=0x0) at /usr/src/sys/kern/vfs_bio.c:4043 #10 0xc05ca4a4 in fq_completed (bp=0xc6a05360) at /usr/src/sys/kern/dsched/fq/fq_diskops.c:307 #11 0xc03bb350 in biodone (bio=0xc6a05360) at /usr/src/sys/kern/vfs_bio.c:4034 #12 0xde2ed9ef in vnstrategy (ap=0xde651ce0) at /usr/src/sys/dev/disk/vn/vn.c:381 #13 0xc034ce1b in dev_dstrategy (dev=0xdcd64850, bio=0xc6a05360) at /usr/src/sys/kern/kern_device.c:349 #14 0xc037af6a in dsched_strategy_async (dp=0xdefe786c, bio=0xc6a05310, done=0xc05ca2f2 <fq_completed>, priv=0xdfc76600) at /usr/src/sys/kern/kern_dsched.c:559 #15 0xc05ca043 in fq_dispatch (diskctx=0xdcd42a00, bio=0xc6a05310, tdio=0xdfc76600) at /usr/src/sys/kern/dsched/fq/fq_diskops.c:323 #16 0xc05c9e05 in fq_dispatcher (diskctx=0xdcd42a00) at /usr/src/sys/kern/dsched/fq/fq_core.c:149 #17 0xc03739f1 in lwkt_deschedule_self (td=Cannot access memory at address 0x8 ) at /usr/src/sys/kern/lwkt_thread.c:283 -- You have received this notification because you have either subscribed to it, or are involved in it.
