In recent coreboot versions, the audio mute button and fan control has stopped working. Whereas you use the same revision from Libreboot, it all works fine and smoothly. This leads me to suspect that someone changed someone without testing, which is real annoying.
Sorry, you hit a problem, and thank you for reporting it. The project is short of testers, so it’d be great if you stepped up or payed some company for it.
The audio mute button technically still functions, but the LED no longer turns on/off. Always just off. Fan control no longer works with Thinkfan. /proc/acpi/ibm/fan doesn't exist any more. I've tried "force loading" thinkpad_acpi, but it doesn't work.
Please attach logs and it’d be great if you could bisect the problem. (Please make sure to have a way to recover, in case a bisect commit fails to boot due to another issue fixed in the mean time.)
It’d be great if you could upload logs to the board status repository with `util/board_status/board_status.sh`.
I'm happy to try and help, but I'm not too familiar with coreboots code. So I'll try my best. There's not too many logs I can really attach. The mute button still works like I said, but the LED just doesn't turn on/off. Could you please let me know where the code would be for this so I can start analyzing it? For Thinkfan, I get the following error: ``` ERROR: ~TpFanDriver: Resetting fan control in /proc/acpi/ibm/fan: No such file or directory ERROR: ~TpFanDriver: Resetting fan control in /proc/acpi/ibm/fan: No such file or directory ERROR: init: Initializing fan control in /proc/acpi/ibm/fan: No such file or directory ``` I couldn't run board_status because I got: ``` Getting coreboot boot log Getting timestamp data Verifying that nvramtool is available Getting all CMOS values Failed to run "util/nvramtool/nvramtool -a", aborting ``` Thanks
