whoa, other_cpus: 0x0000000e, stopped_cpus: 0x00000004

I came upon my machine, locked up. I was able
to drop into the debugger. The last message
out was:
"pmap_lazyfix: spun for 50000000"

When i tried to continue, i got this message instead:
whoa, other_cpus: 0x0000000e, stopped_cpus: 0x00000004
panic: stop_cpus() failed
at line 202 in file /usr/src/sys/i386/i386/db_interface.c
cpuid = 0; 
boot() called on cpu#0

syncing disks, buffers remaining... panic: pmap_invalidate_range: interrupts
disabled

I'm not sure why the 'whoa, other_cpus' message
would come out?

This comes from sys/i386/i386/db_interface.c

Can this provide a clue as to why it was locked up?
I got the vmcore from this, what does one look for
in it?
