Additional info: 5.5 worked 5.7 paniced in the same way as 5.10

Now I built drm-54-kmod-5.4.144 on FreeBSD 14.0-CURRENT #23 main-n255143-271f6d52a60 and it works.

So it broke between 5.5 and 5.7.

I don't understand why you have 'fbd0 on drmn0' printed. Or more exactly why I don't have it ... Is it GENERIC without any tuning ?

jownit commented 2 years ago

GENERIC-NODEBUG no tuning

debdrup commented 2 years ago

As a follow-up from #166 above, core.txt can be found here.

evadot commented 2 years ago

So, I believe this is happening when one have multiple screen with different resolution. I'll try to debug that soon.

So, I believe this is happening when one have multiple screen with different resolution. I'll try to debug that soon.

This is true in my setup. The ThinkPad has an internal screen with 1920x1080, and there is a 4K monitor and a 1920x1200 monitor connected to the dock.

Could you confirm that with only the laptop screen everything work ? I'm not at home this week so testing multiple display is hard right now for me.

Confirmed. Loading the module with the laptop undocked it works. Docking it immediately panics. I also tested having it docked with the external monitors unplugged, it works. If I plug in a monitor in, it panics.

evadot commented 2 years ago

Thanks for confirmation, this will help me to fix this quickly when I'm back :)

evadot commented 2 years ago

@debdrup @jownit Are both your docks usb-c ? I cannot reproduce here with multiple screen and different resolution on multiple machines.

@debdrup @jownit Are both your docks usb-c ? I cannot reproduce here with multiple screen and different resolution on multiple machines.

Mine is. I could try plugging in a monitor directly in the HDMI port on the laptop and see what results I get.

I just tried that. With a 4K monitor plugged in to the laptops HDMI port, it works. Plugging in another monitor in the dock displayport (which is USB-C) panics.

So it seems the problem is with USB-C. Loading drm-54-kmod works.

I'm using this dock.

Should I try to reproduce this too? I'd need to get a USB-C to DisplayPort connector in order to try it, unless I can locate a spare HDMI cable that isn't embedded in a wall.

evadot commented 2 years ago

So, I can't reproduce with an USB-C HDMI dongle. I don't have a dock here.

Anything I can do to help debugging?

evadot commented 2 years ago

Forgot that I had a dock on my work laptop. I managed to find the problem and https://cgit.freebsd.org/src/commit/?id=3cbf6518d6eea08e0fbe6d7c609debac5ab31992 fixes this for me. Please let me know if that fixes it for you too.

That's not the same problem. Can you open an new issue please ? I'll wait for @debdrup to confirm or not that it fixed it for him before closing this one.

Issue #181 opened.

Closing this one now, @debdrup please re-open if my patch didn't fixed this for you, what @jownit is seeing is another problem.
