With GENERIC, I encountered a different panic when the OS woke from sleep:

the time of the panic.
I did not take a photograph. If I recall correctly, the screen froze with a
(red) arrow pointer on a dark/blank background before the lock screen appeared.
The pointer that I normally see with Plasma.
