+ === Original Bug Report ===
I am using an old HP EliteBook 6930p with current Ubuntu.
When the computer is suspended, even after a fresh boot, it does not
wake up: the power comes back, but the laptop is frozen, and does not
respond to ping.
It is working fine with 5.3.0-29, but not with 5.3.0-40 nor 5.3.0-42.
I am holding kernel purge for now, but this is annoying.
