I hope this is the right way to reply. I had a panic, same message, with 
5.x for a long time. Kept posting but no one seemed to be able to offer 
much advice. Just thought I would add that I was mounting something with 
smbfs too, although since I didn't know it was smbfs I was always using 
it... you may be on to something? :) In the end I got fed up and went 
back to 4.x, which has been up twice as long so far BUT I don't have the 
samba share mounted ;) If it's worth trying to see if it panics after a 
while with smbfs, even on 4.x, I could do that.
