I can confirm this bug. Just try mount -t auto /dev/sdxy /mnt
where sdxy is an extended partition. With version 2.17.2-9.1 there is no problem, you just get the error message "mount: you must specify the filesystem type". But from version 2.19.1-2 on mount shows the described buggy behaviour. This also affects busybox and therefore the debian-installer if you try to install debian from a usb-medium as described here: http://www.debian.org/releases/wheezy/i386/ch04s03.html.en The installer mounts one partition after the other looking for an iso-image. The image is on sdb in my case but the installer starts looking at sda1 no matter what. So before it even gets to sdb, the installer tries to mount the extended partition on sda and mount hangs as described, using 100% CPU. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
