and 19 more in 2days+22:44 uptime

Trying to get clear about this....this is an error in the driver, not in 
xfsdump, or
does xfsdump have a problem?  If that's the case, does it only have problems
because it is
run w/root privs?   I.e. -- an unpriviledged user wouldn't see these?

Thanks, sorry to keep coming up w/these... but assume you'd rather know than 
not...
