Yesterday I bought a Radeon RX550 adapter (PCI ID 1002:699f) t=
o replace a dying
GeForce for my desktop. It worked OK all day, but when I tried to suspend t=
he
system at the end of the day, it failed - the system was left running but
unresponsive and had to be reset.
Looking at the logs of the boot which ended with the failed suspend attempt=
, I
see this:
