[Solved] Unable to boot USB after latest mkinitcpio upgrade

I upgraded mkinitcpio today and removed all my block devices for the block hook and regenerated. I boot with syslinux via UUID. It boots fine in Virtualbox when it thinks it's SATA, but when I try to boot off the thumb drive itself it cannot find the root partition anymore, and drops to recovery shell after syslinux. Oddly, adding usb back to the hooks and regenerating doesn't fix the problem either. It worked up until today without a hitch.

Thought I'd troubleshoot on the forums before entering a bug report. Anyone else using a USB stick and not able to boot with the block hook?

SOLVED:
Moved block hook directly after udev hook and it appears to boot from USB again.

Re: [Solved] Unable to boot USB after latest mkinitcpio upgrade

The block hook provides the exact same logic for adding modules that the old usb hook does. Of course adding the "usb" hook doesn't work, because it no longer exists.

You'll need to compare the contents of an initramfs created by 0.11.x to one created by 0.12.0 to figure out what's causing this.

Heh, yes that makes sense the old hook won't work with the new version. Haven't had to look at an image in a long time, I'll try and get around to it.

I also tried booting by block device, (eg. /dev/sdx#) to rule out uuid being the problem, which this successfully accomplished.

I tried going back to 11, however it still won't boot from USB. I also added rootdelay 30 just in case it needed extra time.

Here is the output from the version 11 generated image (with USB hook).
