The integrated graphics card in my Intel Ultra 7-155H, -- "Intel Corporation Meteor Lake-P [Intel Arc Graphics] (rev 08)" -- isn't supported by any of the stable kernels. As far as I can tell, it requires version 6.8 or later. The only available versions that support it (at the time of writing) are 6.11.X. I'm also running ZFS, which requires kernel version 6.10 or lower. This means that no kernel that supports both ZFS and my integrated graphics is available. I've solved this by copying an "old" 6.10.14 from the official repository's Git history to my local overlay. Please keep at least one kernel version lower than 6.11 and above 6.8 in the tree.
I'm sorry, but we're not going to do that. We prune EOL kernels because having them in-tree implies: a) they're okay to use, and b) that we may backport fixes to them. You're free to import such kernels to your local tree. The advice when using ZFS has always been to use LTS kernels. If your hardware needs a newer kernel, either don't use ZFS for it temporarily, use zfs-9999 at your own risk, or manually maintain that kernel in an overlay if such a version even exists. Making such a compromise just for your case isn't an option either, as people have asked in the past we always keep an EOL version around just for the benefit of ZFS. And then, if not ZFS, what about other third party modules? This issue in general was discussed in https://forums.gentoo.org/viewtopic-t-1170342.html, see also my replies there.
