I have an Intel NUC I was using as a media device running ubuntu 20.4, it has an IR receiver which was working perfectly as a "keyboard" until I just updated the system. Now some remote buttons produce no key code at all and others produce huge streams of repeated codes for a single button press. I haven't had time to try looking at it in detail yet, I just thought I'd ask if anyone else has seen this and already have a fix? Maybe booting old kernel will work.
