 Can you try with a -current GENERIC kernel?  I think this has been fixed 
 and will be pulled up before the NetBSD 6 release.  You can get a 
 -current kernel from nyftp.netbsd.org, like this one:
 
 
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201205041410Z/amd64/binary/kernel/netbsd-GENERIC.gz
 
 (This particular kernel will expire off the server in a week or two, but 
 you should be able to find a more recent one if so)
