[Bug 611821] [NEW] Kernel 2.6.35-10 to 2.6.35-12 hang on FDE boot

Public bug reported:

Binary package hint: kernel-package

Ubuntu Maverick 10.10 Alpha-2 x86_64 with Full Disk Encryption.

Kernel updates 2.6.35-10, 2.6.35-11, and 2.6.35-12 hang on boot after entering and posting password for full disk encryption.
The Ubuntu boot GUI loads for a few seconds and then just hangs.

Kernel 2.6.35-9 boots without problems.

In 2.6.35-12 if [Escape] key is immediately pressed after posting FDE
password to switch from Ubuntu boot GUI to text mode boot screen then
system boots up normally. Have not tested if this bypass solution works
with -10 and -11 kernels.
