Hi,

Thanks for the analysis and the advice.
I tested i8042.reset=1 and touchpad's still dead.

Best,
Max

Hi,
Thanks for your time!
Below is the output of dmesg with kernel boot parameter i8042.debug=1
All the best,

Thanks, I'm afraid reading raw i8042 is not my forte though, Dmitry, can
you take a look, and do you see why no ps/2 mouse (or touchpad) is seen ?

psmouse - GET_ID - silence. So we decide there is no mouse.

Dmitry, thanks for the analysis.

So if I understand things correctly, then the aux port also gets
probed for it having a second keyboard attached ? I did not know
that, could it be that this confuses the touchpad?

Have we tried i8042.reset?

No not yet. Maximilien, can you try booting with
i8042.reset=1 on the kernel commandline ?

Hans
