kernel 5.9 no keyboard on PowerBook

[Riccardo Mottola <riccardo.mottola@libero.it>]

Hi,


I just upgraded the kernel to 5.9.0 on my PowerBook G4 - no keyboard, I 
cannot even login. I reverted to 7.0-2 and everything works as expected.


I do not have intermediate kernels, so I cannot tell when exactly things 
broke.


Anyone else experiencing similar symptoms?
