Hello,
I'm coming back to a problem I've on an old machine that has a TPM 1.2 chip.
We already had an exchange of mail on this mailing list about a (few)
year(s) ago, but the problem still exist on 5.17 on debian unstable

And then the console is spammed with several more:
[ 149.636208] tpm tpm0: tpm_try_transmit: send(): error -62
The /dev/tpm0 device error is present, but trousers/tcsd fails with:
avr 25 15:12:06 fornost tcsd[4667]: TCSD TDDL[4667]: TrouSerS ERROR:

An idea?
Kind regards,
