We need some more information in order to debug this problem.

- Did any previous kernel version work fine for you?
- Does the issue arise after performing some specific tpm operations?
- Have you by any chance upgraded/downgraded your coreboot firmware?
- Please share the full output from dmesg.
- Please try a more recent kernel from bookworm-backports to see if the
  problem can still be reproduced. See https://backports.debian.org/Instructions/

Thanks,
  Emanuele
