I tested 5.8.0-57.64~20.04.1 proposed on Focal, and it appears to be working fine. Thank you for the fix.

Commit 528222d853f92 ("media: rc: harmonize infrared durations to microseconds") that needs to be fixed by these two does not exist in 5.8 kernel. The patch author Matthias Reichl also state these are for 5.10 and onward. [Fix] Revert these two patches for groovy. [Test] Test kernels for G-5.8 / F-5.8 can be found here: https://people.canonical.com/~phlin/kernel/lp-1926030-revert-for-ir/ User Ted L confirmed that F-5.8 test kernel can fix the problem. [Where problems could occur] The chance to cause regression can be considered as low since the original patch that need to be fix by these two patches does not exist in 5.8 at all. [Original Bug Report] I use an IR remote with the ir-keytable package. Everything was working fine until kernel 5.8.0-49 was automatically installed by Software Updater on Ubuntu 20.04.2. When any key is pressed on the remote, the key is repeated about 500 times. The kernel is now 5.8.0-50, and the problem persists. Other users on the MythTV mailing list are reporting the issue, and it appears that the problem is related to changes in the following files: drivers/media/rc/ir-mce_kbd-decoder.c drivers/media/rc/rc-main.c b/drivers/media/rc/rc-main.c drivers/media/rc/serial_ir.c It has been reported that reverting the ir-mce_kbd-decoder.c and rc- main.c files to the older versions fixes the problem. /proc/version_signature > version.log: Ubuntu 5.8.0-50.56~20.04.1-generic 5.8.18 lspci -vnvn: 00:00.0 Host bridge [0600]: Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers [8086:590f] (rev 06) Subsystem: ASUSTeK Computer Inc.
