Cannot enter passphrase for cryptsetup after Upgrade to 13.10

[Neelson]

After upgrading from 13.04 to 13.10 i cannot enter my password into the cryptsetup preboot prompt. It says "Enter passphrase:" but i cannot type anything in it although my keyboard works. After forcefully restarting i can choose in Grub "advanced options" and choose kernel 3.8.0-31 instead of 3.11.0-12 and then everything is fine. Because it works with an older kernel i assume that the new kernel is somehow incorecctly configured and that some usb driver for the keyboard isn't loaded early enough. I found https://bugs.archlinux.org/task/17700 where they suggest in archlinux to "hook sbinput in mkinitcpio.conf"
