Cache gone and unable to restore after kernel update in Arch Linux.

[f3bruary]

I updated my Arch Linux and it pulled a new kernel. After I rebooted I noticed some enhanceIO errors and it appears that the setup got nuked.

I re-installed enhanceio-dkms-git from AUR. Followed the Wiki: https://wiki.archlinux.org/index.php/EnhanceIO again. (files in /etc/initcpio/hook, /etc/initcpio/install were gone). Fixed permission errors and re-created the initcpio.

It still won't work.

[f3bruary:]$ eio_cli info
No caches Found
[f3bruary:]$ sudo eio_cli create -d /dev/sda -s /dev/sdb -c my_first_enhanceio
Cache Name : my_first_enhanceio
Source Device : /dev/sda
SSD Device : /dev/sdb
Policy : lru
Mode : Write Through
Block Size : 4096
Associativity : 256
Cache creation failed (dmesg can provide you more info)
[f3bruary:]$ dmesg | tail -1
[ 3021.746817] enhanceio: Cache creation failed: Cache already exists.
[f3bruary:]$ sudo eio_cli delete -c my_first_enhanceio
No cache exists with the name my_first_enhanceio

So I can't create a new cache and can't delete the old one...

I removed all files relating to enhanceio, uninstalled the app, removed files from the hooks and install folder and mkinicpio.conf, then regenerated it, rebooted and it seemed to be gone. Then I installed enhanceio again, followed the wiki, and 'eio_cli info' showed it was working. Then after a reboot it's the same issue again.
I notice in journactl it's executing each enhanceio command twice: http://pastebin.com/dzQXa2st

Is EnhanceIO deprecated ?

Have you tried the command 'eio_cli enable' instead of create, if the cache is already existing?

No, but right now it's broken on the latest kernel (on Arch Linux) anyways. :(
