Thanks for that. It looks like on 5.8.8 it has not loaded the rc keymap at all. It looks like a default mce keymap with the default rc-6 protocol enabled.
So for some reason /etc/rc_map.cfg did not get processed at all. That's super odd. Let's try and see what udevd does when you plug in the device. On 5.8.8 As root, run: udevadm control -l debug journalctl -u systemd-udevd.service -f Now plug in the device. There _should_ be some lines about ir-keytable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901089 Title: Ubuntu kernels 5.4.0-51 and 5.4.0-52 break ir-keytable loading To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
