Public bug reported:
I have a laptop with a defective wifi adapter that runs with iwlwifi and
I was able to use a usb adapter with kernel 7.0.0-28-generic. When 26.04
updated to 7.0.0-29-generic, my brostrend adapter no longer worked and a
panda pau0b adapter could not load its driver either. Reverting to
7.0.0-28-generic allows me to use the usb adapter. Something in
7.0.0-29-generic is preventing these drivers from being loaded.
