--- Comment #1 from naon@disroot.org ---
I have just discovered after months of searching that I recieve this same
error. I have a desktop computer than uses both a AMD WX3100 and a AMD RX570.
When I turn off my monitor connected to either of my graphics cards (an
effective hotplug), then turn my monitor back on, I recieve the error

[drm:drm_dp_mst_dpcd_read [drm_kms_helper]] *ERROR* mstb 000000008ff61da7 port
8: DPCD read on addr 0x60 for 1 bytes NAKed

xorg crashes, I recieve the message

[drm:drm_dp_check_act_status [drm_kms_helper]] *ERROR* Failed to get ACT after
3000ms, last status: 01

and it takes up to 40 seconds for display of the vt to resume. The longer the
monitor remains off, the higher the chance that display of the vt will never
resume after the monitor is turned on, needing a hard restart. This error has
persisted for about 3 months, ever since i've first installed linux on this
computer, on every kernel variation and build I have tried to date. Currently
reproduceable on 5.11.16.
