Actually, if you're having PV errors, it might be the filesystem driver 
that's panic-ing....you'll need to run the output through ksymoops and find 
out where it's dieieng.  If you've corrupted filesystem data, that's the 
much more likely target (although what you're hypothesizing isn't 
impossible, I've just never seen that).
