[SOLVED] Kernel Panic on Install with Encrypted Root

When I attempt to boot into my new arch install with the LVM on LUKS configuration, I get a kernel panic error which states:

not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I’m using systemd-boot, but I don’t think that’s causing this error. Here are my arch.conf, mkinitcpio hooks, fstab, and crypttab:

/boot/loader/entries/arch.conf
title    Arch Linux
linux  /vmlinuz-linux
options rd.luks.name=cde8598b-9065-4177-acb3-75791bbd3287=cryptlvm root=/dev/cryptgroup/root resume=/dev/cryptgroup/swap

/etc/mkinitcpio.conf
HOOKS=(base systemd autodetect keyboard sd-vconsole modconf block sd-encrypt sd-lvm2 filesystems resume fsck)

/etc/fstab

Re: [SOLVED] Kernel Panic on Install with Encrypted Root

Alright, I was able to get it working, and boy do I feel silly. Turns out I didn't need crypttab at all, and I don't need the resume hook in my mkinitcpio.conf because the systemd hook takes care of that for me. I was able to fix the issue by installing intel-ucode, and adding the following lines to my arch.conf:

initrd  /intel-ucode.img
initrd  /initramfs-linux.img

I'm marking this "solved" now.
