I recompiled the kernel and now I'm getting a panic as shown in the
attached textdump. I don't believe it's a real panic as a vmcore file
isn't produced... then again I'm a bit new at the kernel debugging
game and if someone would provide me the necessary steps to get one so
I could link it into kgdb (which I _do_ understand how to use) it
would be much appreciated.

I bet that someone else could reproduce this issue with a fresh
version of -CURRENT.

Again, I'll reproduce this little issue with 8-CURRENT on my VM (I
just got as far as possible as I knew under the circumstances with my
desktop), instead of trying with 7-RELEASE as major changes were done
with locking in 8-CURRENT recently and dtrace was synced back to
8-CURRENT recently as well.
