I also have this on my laptop, using a USB-C to 3xHDMI adapter with 3 monitors.
When I unplug and replug it, sometimes the screen will freeze and I have to
force reboot.
log shows:
i915 0000:00:02.0: [drm] *ERROR* mstb 00000000c152fe9e port 1: DPCD read on
addr 0x4b0 for 1 bytes NAKed
i915 0000:00:02.0: [drm] *ERROR* mstb 00000000c152fe9e port 2: DPCD read on
addr 0x4b0 for 1 bytes NAKed
The machine also dies when resuming from suspend with the adapter plugged in,
but I could not get any log, just guessing it might be the same issue.
my setup:
HP Envy 13 ad110tu (i5-8250U, UHD 620)
Archlinux with kernel 5.16.13-arch1-1 x86_64, KDE Plasma 5.24.3 on Wayland
