Oh, addendum... I didn't see this email regarding an actual panic.
There are two problems here, one of which (the nbufkv lockup) should
be solved by my previous email.
The second problem is this panic you are reporting, and I have no idea
what is causing it so this issue remains open. It could be softupdates,
it could be vinum, or it could be the ATA driver.
What you need to do to help solve the panic is to gdb a debug version
of the kernel image rather then the non debug version so the stack
backtrace contains source line numbers and such.

: After some more time spent with the system. It turns out it
:is softupdates. I can complete the script (which copies /usr/ports to
:a newfs'ed system) without softupdates but with, it will stall and
:then crash. An interesting note, with softupdates, during a stall I
:did a sysctl vfs.hidirtbuffers=500 and it completed, howver, if I do
:this before running the script, it crashes as well (but doesn't take
:nearly as long to do so).
: Included is a traceback of when it crashed witht he hibuffers
:at 500.
