I think that the underlying problem is i2c related. Something i2c doesn't work and the full struct isn't init so we fail later when we try to use it.

I just updated my laptop and thought I could try drm-510-kmod again just for the sake of it. To my surprise it works now... drm-510-kmod-5.10.113_1 on 14.0-CURRENT #41 main-n256399-454adf0fa4d-dirty

[evadot]

Mhm ok, maybe there is a race somewhere, does it works every time ?

[jownit]

I've rebooted a few times now (I have 'kld_list="amdgpu"' in /etc/rc.conf) I rebooted both with it docked and undocked and docking after booting I tried cold booting, both docked and undocked I tried undocking and redocking while running. No more panics so far.. I feels stable, more stable than drm-5.4 even, which would occasionally panic while booting

[evadot]

Ok seems good then, let's close this and if you encounter it again in the futur just re-open (if it's another panic please open a new bug).
