Bug Description
[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. 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:/
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:
