These are debug messages and can be ignored. I left this in to get more 
info about storms/locks Steve and me is seeing. Especially cdrecord and 
friends are testing many commands on drives and some of them just fail 
because drive doesn't support them. I'll switch this back of once we have 
issues resolved.
