Have you googled for this errors? Have you tried to disabled the device mapper (if nothing depends on it)? Sometimes it helps to boot from a CD (e.g., Debian installer, Knoppix), and see what happens with a different configuration. If the error is still there you can concentrate on the similarities between your configuration and that of the CD; if the error goes away you concentrate on the differences. Regards, Bernardo

etch: cannot mount usb hd
Hello everyone, I cannot mount an usb hd when it was connected while switching on my machine. The message is the famous "already mounted or busy". I found many things in google, but nothing matches my problem. symptoms: - device is detected on startup (currently /dev/sdc with 3 partitions sdc1-3) - mount -> usb hd not in list, so not mounted yet - lsofs -> empty for both the device (/dev/sdc2) and the mount point - tried different mount points (no shell / file manager blocks the mount point - sudo mount -a / open disk in konqueror-> "already mounted or busy" After restarting the usb hd I can mount its partitions without any problems. This is true for both mounting via fstab entry (my backup partition should be auto mounted on startup without any desktop support) and the user partition which is auto mounted by kde. Tanks for any help Jörg
