[SOLVED] ERROR: 'UUID=...' device not found

Howdy,

After upgrading this morning, when I try to boot up I get an error:

starting version 239
ERROR: device 'UUID=f46a03aa-b1db-4ee2-9c74-d71150abc71a' not found. Skipping fsck.
mount: /new_root: can't find UUID=f46a03aa-b1db-4ee2-9c74-d71150abc71a
You are now being dropped into an emergency shell.

I CAN boot using the fallback initramfs image. I'm not sure how to debug this since I can't find any devices named /dev/sd*.

Any ideas?

Re: [SOLVED] ERROR: 'UUID=...' device not found

Please provide your "/etc/mkinitcpio.conf" and the output of "mkinitcpio -P" and "lsblk -o +UUID".
Also do not truncate the disk's UUID that cannot be found. It may very well be essential to the issue.

Re: [SOLVED] ERROR: 'UUID=...' device not found

Added to my original post

Please provide your "/etc/mkinitcpio.conf" and the output of "mkinitcpio -P" and "lsblk -o +UUID".

Here's my mkinitcpio.conf (I've removed the comments for clarity)

MODULES=()
BINARIES=()
FILES=()
HOOKS=(base udev autodetect modconf block filesystems keyboard fsck)

The output of "lsblk -o +UUID"

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT UUID
sda      8:0    0 238.5G  0 disk
├─sda1   8:1    0   500M  0 part            0CD7-29EC
├─sda2   8:2    0   128M  0 part
└─sda3   8:3    0 237.9G  0 part            6A7CDA3A7CDA012D

├─sdb1   8:17   0  1024M  0 part /boot      E0E0-CD52

and finally, "mkinitcpio -P"

That looks correct. I am indeed booting from an external harddrive

EDIT: The workaround listed in the bug fixes it for me. In summary, add "usb_storage" and "uas" to MODULES array, then rerun "mkinitcpio -P".
