rebuilt kernel and can no longer boot

[o5gmmob8]

I reinstalled gentoo-kernel with the hopes that if I made any changes to the configuration, they would be reverted and I would have sound again. After copying the kernel, init, and other files to the EFI partition, I can no longer boot. I'm using efibootmgr to manage boot entries and just booting the kernel directly since I had issues with GRUB.

My root filesystem is ZFS on LUKS. I left the dracut configuration intact and as far as I know, the zfs and luks support should be built in. When booting, the init does prompt me to unlock the root partition, but it fails to mount the root partition which is ZFS. It appears that ZFS support is not working.

Any ideas?
