Title:
Focal (20.04): IR Remote Keys Repeat Many Times Starting with Kernel
5.8.0-49
Status in linux package in Ubuntu:
Expired
Bug description:
The bug reported at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926030 affects
Focal (20.04).
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.
