I can reproduce this bug on my squeeze system with backports kernel 3.2.0-0.bpo.3-686-pae too. Not with "-t auto" but if I use some filesystem (e.g. ext2/3/4, reiserfs) in the mount command.
mount -t ext3 /dev/sdxy /mnt With kernel 2.6.32-5-686 I get the ususal "mount: wrong fs type, bad superblock on /dev/..." error message. There is a similar bug report for the 3.2.0 kernel on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1032874 So to reproduce this use squeeze with the backports kernel or wheezy with stock 3.2.0 kernel. Try to mount an extended partition (=the partition that contains the logical partitions) using filesystem type ext2/3/4 or reiserfs. e.g. mount -t ext3 /dev/sda4 /mnt The mount process will hang using 100% CPU; kill -9 won't kill the process. I didn't try all the available fs types but for example "-t xfs" gives the correct error message and does *not* hang the mount process. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
