Using ir-keytable (in the ir-keyable package on Ubuntu) you change the protocol and see what's being sent. However I guess the problem is that IR edges aren't being reported until triggered by more IR edges. > > Can you reproduce the issue on a more contemporary kernel? > > > > Yes.

There is a lot code churn so it would be very helpful to have it reproduced on a recent kernel. Unfortunately your bisect wasn't entirely useful. You ended up at e40b1127f994a427568319d1be9b9e5ab1f58dd1. Unfortunately that commit introduced a bug which was not entirely resolved until 9800b5b619cd9a013a6f0c7d5da0dbbc17a5af30. If you do a bisect again it would useful to skip anything between those commits. Also is the issue intermittent or is your last key press *always* missed?
