Computer not sleeping correctly with new kernel

I've been using Arch for a few months now and hit my first serious bug -- my laptop doesn't go to sleep

I imagine this is due to being on the bleeding edge.

Anyway, thanks to the great documentation I think I have isolated the problem:

```
# journalctl -p 0..3 -xn
-- Logs begin at Tue 2015-08-25 11:42:43 MDT, end at Wed 2015-10-14 23:51:23 MDT. --

Oct 14 23:34:56 localhost kernel: PM: Some devices failed to suspend, or early wake event detected
```
It sure looks to be a kernel issue to me! But when I try to downgrade the kernel:

```
# cd /var/cache/pacman/pkg
# sudo pacman pacman -U linux-4.1.6-1-x86_64.pkg.tar.xz
loading packages...
error: 'pacman': could not find or read package
warning: downgrading package linux (4.2.3-1 => 4.1.6-1)
```

It doesn't look like I can downgrade. The [wiki on downgrading](https://wiki.archlinux.org/index.php/Do … g_packages) suggests using the installer "If you are unable to boot after a kernel update," -- but I'm not that desperate

Is there something I am doing wrong?

Some notes:

Re: Computer not sleeping correctly with new kernel

# sudo pacman pacman -U linux-4.1.6-1-x86_64.pkg.tar.xz

You typed pacman twice.

Re: Computer not sleeping correctly with new kernel

Oh my god, I can't believe I did that haha. That was all I needed to do! Thanks

How do I mark this as closed?

Edit: submitted a bug to the linux kernel here: https://bugzilla.kernel.org/show_bug.cgi?id=105991
