Re: cache_lock: blocked on 0xd0129580 "ttyp4" (after issuing reboot from remote ssh shell)

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:Hello!
:
:	I wanted to reboot DragonFly_Stable remotely and machine got hung. Here 
:is the sequence from console:
:
:- rebooted by me
:- exiting on signal 15
:- waiting for vnlru/bufdaemon/syncer - all stopped
:- syncing disks... done
:and then
:
:[diagnostic] cache_lock: blocked on 0xd0129580 "ttyp4"
:
:Machine is still responding to pings from network! Can not get into ddb 
:even though CapsLock and NumLock are still responding.
:
:Interesting...
:After pressing Ctrl-Alt-Del I got:
:Shutting down daemon processes:.
:Saving firewall state tables:.
:Waiting (max 60 seconds) for system thread vnlru to stop... stopped
:Waiting (max 60 seconds) for system thread bufdaemon to stop... stopped
:Waiting (max 60 seconds) for system thread syncer to stop... stopped
:
:and then fast reboot.
:
:P933, 512MB, Abit BX133-RAID mobo
:3Ware 7006-2 (2 disks in mirror)
:Dfly-Stable sources as of Monday evening (UTC) 29th Nov 2004
:and ACPI mode as per default.

    Hmm.  If this ever happens again, see if you can ctl-alt-esc
    into the debugger and panic it out to get a kernel dump.
