I've upgraded my CURRENT laptop to 82d8a5029a80 and noticed it couldn't resume
from suspend anymore.  After discussing it on mailing lists and bisecting
changes between previous version I figured out that RANDOM_ENABLE_TPM kernel
option is the culprit.  Removing it from kernel makes the system to work as
expected.
