	My server runs a up to date netbsd-7 kernel built with -O0 -g and some 
diagnostic options. It has rebooted three time this evening with 
following message :

	I have disabled altqd to check if my first panic comes from altqd (ffs 
cooruption should come from altqd related panic). If I remember, I 
haven't seen panic without altqd on this server.
