Hardware is Ryzen 7 2700x, Sapphire Technology Radeon RX 480, IIyama ProLite
XB2380HS connected via DVI.

It looks like "dm_dp_aux_transfer" is used to setup DisplayPort, =
using "struct
drm_dp_aux_msg =E2=80=94 DisplayPort AUX channel transaction". Now, wi=
th my hardware I
don't have any monitors connected via DisplayPort. Is that relevant?

I patched in a "printk("msg->size =3D %d\n", msg->size=
);" and it displays the
result twice, which is curious.

# dmesg | grep -i "msg->size"
[    9.469511] msg->size =3D -5
[    9.469803] msg->size =3D -5

Anyway, full "dmesg" attached.

I found that udevd is running "/usr/bin/xcmddc --i2c /dev/i2c-7 --iden=
