Title:
IR receiver broken by 5.8.0-55, worked in -48
Status in linux package in Ubuntu:
New
Bug description:
On intel nuc used as media server running ubuntu 20.04, the IR remote
broke in kernel 5.8.0-55. Running ir-keytable -t shows that a single
IR button press spews key down codes forever, and never does a key up.
Going back to kernel 5.8.0-48 makes the remote work properly again.
Here's a sample of the working output:
Testing events. Please, press CTRL-C to abort.

The key down part just repeats over and over in the busted kernel.
