kldload Freeze after 30 minutes

The attached picture is on an external monitor connected to the secondary
Nvidia GPU (that cannot drive the internal screen).

What you see is a `tail -F /var/log/messages` on the left and the `kldload
i915kms` on the right.

Upon the kldload call the primary notebook screen turns itself off immediat=
ely.
The xorg system still reacts to a degree. I can still interact with the mou=
se,
switch windows focus, mark text etc..
I cannot get any keyboard input (is that still giant locked?).

You may also note that the Powerline clock is 30 minutes past the i3status
clock (that's how long I waited after the kldload call). I'm assuming i3sta=
tus
does a system call that runs afoul of the deadlock that keeps kldload from
completing.

The system runs on an i7-9750H with Coffeelake-H UHD Graphics 630, accordin=
g to
`pciconf -lv`.
