Bug Description

during cdrom-detect in the omap4 server install sda1-sda5 from a former install on the USB media as well as mmcblk0p1 and mmcblk0p2 are probed as installation media by looping through these devices and mounting them. in case of the mentioned image the loop hangs at sda3 which is an extended partition, in the processlist there is an unkillable mount for /dev/sda3 with iso9660 filesystem

zeroing out the partition table on the USB disk before running the install makes everything work fine

digginmg deeper i guess this bug should actually be against list-devices from debian-installer-utils, it should not return extended partitions in its list

From a belt-and-bracers perspective (not to mention that it really shouldn't break like this), mount probably shouldn't hang when asked to try mounting an extended partition either. :P
