I confirm that I was only using extlinux for preparing USB boot sticks etc, and not booting the host itself via extlinux.
I have now hit the bug again on another machine, this one i386. Here is a run with set -x turned on in /usr/sbin/update-extlinux: ----------------------------------------------------------------------- # dpkg -i /var/cache/apt/archives/linux-image-2.6.32-3-686_2.6.32-9_i386.deb (Reading database ... 272798 files and directories currently installed.)
