I see a similar issue on Lenovo Thinkpad P50. If TPM/Security Chip is on in BIOS, I cannot turn off the computer in the normal way. I seems to shot down and screen becomes black, but it is still running (hot) and power led is on. I can then turn if off by pressing power button for 5 seconds. I didn't see this issue before upgrading from 20.04 to 22.04.
