shutdown screen photo
When I try to power off my machine, it shows the usual shutdown messages and
the screens turn off, but the machine is still powered on. The virtual console
shows a kernel NULL pointer dereference at address 0.
I run Arch Linux.
The bug occurs even if I never run X. I can turn on the machine and immediately
try to shut it down, and the same bug still occurs.
This bug occurred since I upgraded linux 5.4.15.arch1-1 to 5.5.1.arch1-1. I now
run linux 5.5.3.arch1-1 and the bug still exists.
My graphics card is Gigabyte Radeon RX VEGA 56 GAMING OC 8G, connected to six
monitors.
A photo of the screen at shutdown is attached. I think these are the relevant
lines for this bug:
