Looks like between bullseye and bookworm TPM support switched from
modular to built in, so the old workaround will not work without a
kernel rebuild.
bullseye:~# grep TPM /boot/config-5.10.0-25-amd64
CONFIG_TCG_TPM=m
CONFIG_HW_RANDOM_TPM=y
CONFIG_TCG_VTPM_PROXY=m
bookworm:~# grep TPM /boot/config-6.1.0-11-amd64
CONFIG_TCG_TPM=y
CONFIG_TCG_VTPM_PROXY=m
I tried another workaround that appears to work.
Disable the TPM in the BIOS. It is in the BIOS setup under the
"Security" tab: "Security Chip". I set that to disabled and "systemctl
suspend" now looks like it works, all the keyboard lights go out.
Pressing power resumes normally.
