Copying tech-kern this time.
Here's the bt output:

User-level: pid 6.1
And here's the dmesg:

This is a generic release-3 kernel. All I've done is I've changed some

thread I've been following recently. I also have softdeps set.
Also, I notice this because an ssh session no longer responds to

(default is 1) so it doesn't cause a panic (I had that problem
This may be related to some other open bugs, but I'm not sure. I could
try a -current kernel I suppose.
