Seems the tpm part is not foolproof yet. And me foolishly thinking I could use this chip for something at last…

Agreed. rngd used the TPM one time successfully, now it's reporting the same message.

The right solution for TPM usage is the tpm-rng module which is coming in Linux 3.7. In the meantime, you may have to check to see if you have tcsd running (which conflicts with rngd if tpm-rng is not available.)

nope, no tscd running (or installed)
