Hi all. Just another "me too" - I've just been bitten by this bug while trying to install testing (stretch) using the netboot install method i.e.:
ftp://ftp.uk.debian.org/debian/dists/stretch/main/installer-i386/20150828/images/netboot/debian-installer/i386/linux and ftp://ftp.uk.debian.org/debian/dists/stretch/main/installer-i386/20150828/images/netboot/debian-installer/i386/initrd.gz I was trying to install onto a partition which already contained a previous debian (wheezy) installation and the installer hung while trying to create the ext4 filesystem. I managed to get round the problem by using dd to write zeros to the first 50MB of the destination partition and then restarting the installation procedure. HTH, Jaime
