We are using locking ranges and these partitions are mapped onto these ranges. We're try too with a locked range without any partition inside an the system tries to access the locked range. We're wondering why kernel? blkid? is trying to get info from a locked range?? The outcome is a SATA link in 1.5Gbps after a long time boot. In windows or MacOSx works in other way. Thanks! Jorge
