I have an Ubuntu 12.04 x64 server. The hard disk is encrypted using LVM.
With kernel 3.8.8, the server works fine - I am asked to enter the
password and can boot the system.
Any kernel above 3.8, e.g. 3.9/3.11 (I didn't try many) prevents me from
entering the password. It seems the attached USB keyboard is no longer
being read from or the system is hanging.
I can however switch between the kernels in GRUB - it's only after the
kernel has been selected and the password screen is displayed that the
system hangs.
I'd like to help in nailing down the bug but I'm at a loss what to do
here as I can't get to any console or kernel logs.
Regards,
Bjoern

Have you tried adding the usb keyboard module to
/etc/initramfs-tools/modules and rebuilding your initrds?
