Hi everyone,

I have the same issue on a ThinkPad T460s (suspend works only half way,
reboot and poweroff stop just short before actual shutdown).

I bisected the problem to the TPM driver. Blacklisting the module in
modprobe.d fixed the problem for me.

Sample configuration: /etc/modprobe.d/blacklist-tpm.conf

# Prevent TPM from loading. It breaks suspend and power cycle.
blacklist tpm
blacklist tpm_crb
blacklist tpm_tis
blacklist tpm_tis_core

Greetings
Felix Rublack
