Hi All,
With a recent update i got de new sys-kernel/raspberrypi-sources kernel 6.1.21 and decided to give it a go, but so far this has not been successful.
My current kernel is sys-kernel/raspberry-sources 5.10.63 which has all required modules built-in. I copied it's .config to the 6.1.21 directory, and used make oldconfig to adapt it to the new kernel. After that i build it with make zImage and copied it to /boot/gentoo6.img, and ran make dtbs and make dtbs_install.
Now, if i configure /boot/config.txt to use this gentoo6.img kernel image i see the kernel booting (so far so good ...), but it stops because it can't find it's SDcard which contains it's root filesystem. I've checked all MMC related drivers and they are available. As a method for troubleshooting i even enabled all MMC drivers to see if that helps, but it didn't.
This are some relevant parts of the kernel config:
