(In reply to Manasi from comment #32)
the panel is definitely not on when drm tries to link train, ie. the monitor is
turned off. Given this, I wonder if this is even an issue anymore?

In other words, since the monitor is off when I type a few keys on the keyboard
to wake up the card(which it thinks it already put the monitor to sleep), then
drm trying link-training with a monitor that it turned off(from the monitor's
button that is, not unplugged from power though) would always fail, right? But
as soon as monitor is turned on, then it re-linktrains and works fine. So, is
it even an issue? I guess Comment 25 was right, it's just the log messages
saying when link training failed. If it weren't for the other two side-effects
(see Comment 26), it wouldn't really be an issue and I guess there's nothing
you can do, unless the kernel does not send a uevent reporting that the link
training succeeded, but if it already does, well then I'm stuck with those side
effects.
