Hi,
with a -CURRENT kernel built today I am consistently getting a panic
during shutdown. Unfortunately a debug kernel refuses to do a core
dump, so I only have a naked stack trace:
panic: lockmgr: thread 0xc1918720, not exclusive lock holder 0xc06b5660 unlocking
#0 0xc04fc40a in doadump ()
#1 0xc04fcaac in boot ()
#2 0xc04fce03 in poweroff_wait ()
#3 0xc04eff3c in lockmgr ()
#4 0xc054b2b2 in vop_stdunlock ()
#5 0xc054b15a in vop_defaultop ()
#6 0xc05e2f73 in ufs_vnoperate ()
#7 0xc0555cd8 in vput ()
#8 0xc05d3a86 in ffs_sync ()
#9 0xc0558a5d in sync ()
#10 0xc04fc5a4 in boot ()
#11 0xc04fc1bf in reboot ()
#12 0xc0632372 in syscall ()
#13 0xc0622fdd in Xint0x80_syscall ()
This panic occurs when I shut the machine down with all filesystems
mounted. I can avoid it when I go to single user mode and umount all
filesystems first.
Please let me know if I can provide further information.
Regards
-Thorsten
