I have also discovered that sometimes the first umount works, = but a subsequent umount (preceded of course by a mount) also freezes. In addition, I also get an occasional freeze-up when issuing the mount = command. If I don't umount at the commandline, but instead call a reboot, the = file system umounts fine - question: since I have mounted the MTD manually, = is it considered part of the file system to be umounted when the machine shuts down? This is more a nuisance, as are the occasional freeze-ups I experience = just accessing the DOC once mounted, but since it's a departure from the = previous good performance, perhaps it's worth looking into?
