You have been subscribed to a public bug:
After locking the screen to leave the computer for a few minutes, I come
back to a computer that is freshly rebooted. It usually happens 1 out of
4 or 5 times when locking the screen.
This only happens when my laptop (Lenovo T470s, also seen with T490) is
connected to my USB-C dock. The problem has been observed with 18.04,
19.10 and 20.04.
/var/log/syslog contains:
