Bug Description

I think that after latest kernel update to Linux 5.8.0-49-generic there is an issue related (at least) to IR remote control input devices. After a key is pressed the event is repeated 95 times.

This is not related to lirc. This behaviour can be seen by utilizing evtest. After I have pressed a key there are several events recognized by evtest:

$ evtest

This bug affects me as well with the mentioned kernel and the next in line:
ubuntu kernel (affected): 5.8.0-49.55~20.04.1
ubuntu kernel (affected): 5.8.0-50.56~20.04.1

With the ubuntu provided mainline kernels (via mainline) the problem does not occur:
mainline kernel (not error): 5.8.0-050800.202008022230
mainline kernel (not error): 5.8.1-050801.202008111432

If during automatic repetition I press another key, this key is then repeated instead but the "counter" is reset and it is repeated another approx. 100 times.

The "value" of the automatically repeated key is "2". The manually pressed key has a value of "1".
