** 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. 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.
