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.
