hi,

FreeBSD epsilon.ury.york.ac.uk 5.0-CURRENT FreeBSD 5.0-CURRENT #10: Fri Jul 26 13:32:52 BST 2002     root@epsilon.ury.york.ac.uk:/usr/obj/usr/src/sys/EPSILON  i386

Had this panic twice with current -current on an uniprocessor machine and
kernel. Dumps still don't work... Both occurances, i had an ssh running, a
portupgrade in progress, and the dnetc client running in the background.

panic: KSE not on run queue
panic: from debugger
Uptime: 1d1h26m12s
Dumping 127 MB
ata0: resetting devices ..
panic: mi_switch: switch in a critical section
Uptime: 1d1h26m12s
panic: witness_destroy: lock (sleep mutex) pseudofs_vncache is not initialized
Uptime: 1d1h26m12s
panic: _sx_xlock (shutdown_post_sync): xlock already held @ /usr/src/sys/kern/kern_shutdown.c:341
Uptime: 1d1h26m12s
panic: _sx_xlock (shutdown_post_sync): xlock already held @ /usr/src/sys/kern/kern_shutdown.c:341
Uptime: 1d1h26m12s
...etc...

traceback from ddb is:

panic
runq_remove
remrunqueue
schedcpu
softclock
thread_loop
forkexit
forktrampoline

Thanks

Gavin
