I think this is spurious. I also see the same message.
As for the slow boot and wakeup: if you remove rhgb quiet you can see the messages while the system is booting. On this 5-years old laptop, there was a 45 sec. delay related to TPM support. You haven’t shown the relevant section from bootctl or mentioned any hardware details.
Slow startup issues may not be specific to Fedora – systemctl mask dev-tpmrm0.device or maybe you need sudo systemctl mask tpm2.target.
