Since my kernel got upgraded to 6.12 not long ago I frequently see messages related to rc-cec
in the journal, like this:
Jan 15 15:24:51 host01 kernel: Registered IR keymap rc-cec
Jan 15 15:24:51 host01 kernel: rc rc0: DP-3 as /devices/pci0000:00/0000:00:02.0/rc/rc0
Jan 15 15:24:51 host01 kernel: input: DP-3 as /devices/pci0000:00/0000:00:02.0/rc/rc0/input146
Jan 15 15:24:51 host01 systemd-logind[1456]: Watching system buttons on /dev/input/event11 (DP-3)
Jan 15 15:24:51 host01 Xorg[1663]: (II) config/udev: Adding input device DP-3 (/dev/input/event11)
I tried to ignore these as long as they have been showing up during boot only or when screen resolution got changed using xrandr
, but today I noticed that these repeat every 30 secs or so when my screen saver is active. Which then floods the journal.
With my previous 6.11 kernel I would get these messages only once during system startup.
I tried blacklisting modules cec
and rc_core
, but it seems that these cannot be easily blacklisted. Required dependencies of something else, I guess.
These messages are specific to an external monitor being connected through HDMI - when using DP there are no such messages. Probably because there is no CEC over DP available …
On the Arch Linux Wiki I found some information on HDMI and CEC specific to Framework laptops, but that hasn’t really helped, either.
Any insight welcome, and if only to provide more information which I could include in a kernel bug report.
