is dumping broken again on current?

[Ben Kaduk]

Hi all, 

I have been trying to track down a panic upon unload of snd_ich, and it 
seems that something in the past week broke core dumps -- I got one useable 
dump from a week ago, but all the dumps I've gotten from today's current 
have failed to load with an infinite loop of:
kgdb: kvm_read: invalid address (0xf0)

Is anyone else seeing this, or is it just my system that's messed up?
