Hi Nicholas, thanks again for your response.

In my new year holidays, I built the upstream (not Debian)
5.10.6 kernel and saw what happend. The situation got better,
* booting always succeeded (at least I did not observe it)
* tpm error persisted
* I did "systemctl poweroff" immediately after I got "login:".
  The shutdown behavior was very strange, many systemd services cannot be
  stopped cleanly and timeouts occurred many times. I cut the power line
  after waiting 5 minutes or so.

I'd like to see the situation again after the upstream version gets 5.10.10 or
so, because, for I now have very little (or no) trust on the upstream (not Debian)
kernel as

* arm64 kernel does not boot at all on raspberry pi 4B on USB MSD
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977694
* arm64 kernel did not boot on raspberry pi 4B on SD card,
  (all usual booting devices did not work). It seems fixed in upstream 5.10.6
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977645
* wireless network does not work on raspberry pi 4B
  (this has not been reported as booting on my raspi has not been confirmed
  on any Debian kernel).

Simply, I am tired of seeing if 5.10.? kernel works normally or not on my machines.
I have seen little problem in Debian 5.9.* series.
Since 5.10 is LTS, maybe 5.10.10 or 5.10.20 will gets as good as 5.9.15.
I will stick to Debian 5.9.15 kernel on my amd64 notebook and raspi4b
for a while...
