xl0 and SNAP004

Hi all,

I cvsuped my tree to HEAD last Sunday but the resulting kernel panic'ed
as soon as ifconfig xl0 was ran. I have the vmcore saved but had to
revert to 5.4 as I needed to use the box. I've downloaded the SNAP004
iso and copied the kernel from base to test it before attempting a real
install, and this what I've seen. No panic but some kernel messages
have poped up:

sleepable locks held: Jun  8 17:30:37 scienide kernel: exclusive sleep

Is this a known problem? I don't see any recent commit to if_xl.c so I
assume the issue is still there in HEAD.

Cheers,
