Right; I was just reviewing the list of updated files and noted
src/sys/kern/kern_malloc.c, and its svn log showed:

With INVARIANTS panic immediately if M_WAITOK is requested in a
non-sleepable context.  Previously only _sleep() would panic.
This will catch misuse of M_WAITOK at development stage rather
than at stress load stage.

And if we were still going in to the office, I'd discuss it with Gleb.  :-)

But in the mean time: I'm not a committer; I didn't cause the error.
Seems I can't try running head now with a GENERIC kernel.

Peace,
