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 immediately.
The xorg system still reacts to a degree. I can still interact with the mouse,
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 i3status
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, according to
`pciconf -lv`.
