>Synopsis: panic: kernel diagnostic assertion "__mp_lock_held(&sched_lock)
>== 0" failed
>Category: kernel
>Environment:
System : OpenBSD 5.4
Details : OpenBSD 5.4-current (GENERIC.MP) #117: Sun Nov 3
11:42:47 MST 2013
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC.MP
Architecture: OpenBSD.i386
Machine : i386
>Description:
I left the machine, with X running and locked (xlock, mode
lightning). I came back to find a ddb{0}> prompt.
I copied the trace information, but there was too much in the ps
listing to copy (no serial port on this machine, so no serial
console). I did copy the one line from ps that began with "*";
it's after the traces.
I needed the machine, so rebooted it, but if you need more
information, let me know and I'll try to get it.
Recent e-mails have accused apmd of troublemaking; it was running
with flags "-aC".
