I haven't seen this, but if this is a regression I also have not run anything later than 4.15-rc1 right now. > 2. How do I find out, what TPM firmware version is installed? fwupd will tell you.

It supports both a "1.2" and a "2.0" firmware. It is independently flashed from a separate TPM payload that is distributed on LVFS.
