lwkt & a fatal trap

[Adam K Kirchhoff <adamk@xxxxxxxxxxxx>]

I upgraded my system this afternoon.  Built world, build kernel,
installed kernel, rebooted, and got this:

I last updated my system last Friday.  

/usr/src/UPDATING doesn't say anything about lwkt, so I'm not sure what,
specifically, has changed that might cause this.

Any ideas?
