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).

    r8152 6-1.3.3:1.0 enx3c52821a24c3: renamed from eth0

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?
