Description

I have recently encountered a bug in coreboot where if you reboot the computer, the keyboard power light will stay turned off after it turns back on. Where if you do a clean boot, the light turns on.

I am unsure whether this is a coreboot or payload issue. I am using GRUB as my payload.

Just run the reboot command in Linux and it should be reproducible.

Priority set to Low as it doesn't affect usability all too much.

Hi I also noticed that. Which kernel are you using? I didnt update coreboot for long only system. And if I recall corectly it was not there before.

I tried using 5.15.152 up to 6.6.0. I don't think the kernel would have anything to do with this though.
