Just FYI, I see this on a few boxes including the 7-BETA2 I'm writing 
this on. None of them has a carp interface though. What I find 
interesting here is that none of them are able to run a SMP kernel 
without crashing (no panic, they're just frozen completely).

Perhaps it is a coincidence, I don't know, but I am very interested in 
your findings and have testbeds if you need.
