[f3bruary]

I think this is what happens when you update the kernel. Try #99

[louy2]

Is this resolved? It is still a jarring warning in Arch Wiki. https://wiki.archlinux.org/index.php/EnhanceIO

As of October 2015 EnhanceIO is completely broken on newer kernels.

[F1nny]

I'm wondering the same? EnhanceIO looks to be dead just based off the git activity? I was forwarded here from the arch wiki and thought it must have been resolved by now haha, so assuming the project is dead in the water? Major bummer was was looking for the best in-place ssd caching method and this seemed to be it.

[lanconnected]

EIO is abandonware, but there are some alive forks. You could try mine for example https://github.com/lanconnected/EnhanceIO .
