dmesg: DRM call stack

Greetings,

I am using kernel 4.19.8, I have two 4K panels which have DP1.2 inputs as w=
ell
as an AMD RX560 GPU[1]. I am experiencing an issue where my machine softloc=
ks
when they are disconnected & subsequently reconnected. If the monitors =
are
power-cycled ,or the DP cable is hotplugged, my kernel log slowly accumulat=
es
messages like "*ERROR* [PLANE:36:plane-0] flip_done timed out" me=
anwhile my
graphical environment hangs, waiting for the pageflip which never successfu=
lly
happens. One of my monitors also happens be HDMI2.0 capable, and when conne=
cted
via HDMI that monitor *does not* lock up the machine in this way, so I beli=
eve
this issue to be DisplayPort specific.

Attached is a dmesg from a recent session exhibiting such a softlock, the
relevant portions are near the end. All my softlocks have `RIP:
0010:prepare_flip_isr+0x5f/0x70 [amdgpu]` in common. I will note that the
driver does seem to at least partially initialize the monitors upon
reconnection, as they do not display "no signal" nor enter sleep =
mode.
