Bug Description
The Internal display does not work. External monitors connected via Thunderbolt down continue to work.
The trackpad does not work. The keyboard does work.
The Ethernet on the Thunderbolt dock does not work.
Booting the 5.11 kernel allows everything to work.
I'm not sure how useful the automatically-

I note that /dev/input/event7 to event26 are missing with kernel 5.13.
The Thunderbolt dock Ethernet seems to be this device (missing with kernel 5.13).

I see what looks like the laptop's internal ethernet showing up though. I didn't think to move the Ethernet cable to that port to see if it would work.
My external monitors (BenQ FP937s and Samsync SyncMaster) show up for both kernels. Interestingly, I don't see the internal panel showing up under either kernel? But it works with 5.11 and not with 5.13.
I only see this with 5.11:
(II) modeset(G0): using drv /dev/dri/card0
And then some EDID probing, that maybe includes the internal panel?
