** Description changed: - 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. + [Impact] + Patch: + * media: rc: fix timeout handling after switch to microsecond durations + * media: rc: ite-cir: fix min_timeout calculation + + Were applied to Groovy with our stable update process (bug 1918516) + + User reported that IR Remote key press will be repeated for multiple times + with these patches applied. + + Commit 528222d853f92 ("media: rc: harmonize infrared durations to + microseconds") that needs to be fixed by these two does not exist in 5.8 + kernel.

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.
