Unfortunately (or fortunately, depending on how you look at things) I
can no longer panic my system with -CURRENT from March 8th. Instead, I
get make to dump core while doing (cd /usr/ports; make clean). This does
not change with snd_hda being loaded. I will cvsup and run overnight
test just to see if anything changes with this commit.
