Hi!

Yesterday some processes on my -current/3.99.16 hung in vnlock.
One was a bulk build in a sandbox (i.e. null-mounted /usr/pkgsrc)
and the other was a 'echo /usr/pkgsrc/*/libetpan' (or similar).
Both processes were unkillable, and other processes trying to
access /usr/pkgsrc hang too.

I switched to ddb and 'reboot 0x104'ed, so I have a core dump.
I also have a kernel with symbols.

What can I do to debug this further?
Or is someone else interested in debugging this problem?

Thanks,
 Thomas
