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:

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