I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.
Can you test the following kernels and post back? We are looking for the first kernel version that exhibits this bug: v3.8.13: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13-raring/ v220.127.116.11: http://kernel.ubuntu.com/~kernel-ppa/mainline/v18.104.22.168-raring/ v22.214.171.124: http://kernel.ubuntu.com/~kernel-ppa/mainline/v126.96.36.199-raring/ v188.8.131.52: http://kernel.ubuntu.com/~kernel-ppa/mainline/v184.108.40.206-raring/ v220.127.116.11: http://kernel.ubuntu.com/~kernel-ppa/mainline/v18.104.22.168-raring/ v22.214.171.124: http://kernel.ubuntu.com/~kernel-ppa/mainline/v126.96.36.199-raring/ You don't have to test every kernel, just up until the kernel that first has this bug.

Expected behaviour: after max. 1-2 minutes, the prompt to enter the disk encryption passphrase should appear. Workaround: while still in grub, enter the advanced options and boot kernel version 3.8.0-19, which shows expected behaviour. The bug seems to appear with kernel version 3.8.0-29; kernel version 3.8.0-19 works. Both vanilla Ubuntu 13.04 and Xubuntu 13.04 are affected. The workaround works for both Ubuntu variants.
