It can't solve such an issue all the times.

[root at archlinux rocketmouse]# downgrade linux
Available packages:

   1) linux-3.15.3-1-x86_64.pkg.tar.xz (local)

The OP could use downgrade, but if you e.g. want to downgrade from
Ardour 3 to Ardour 2 you're screwed.

[root at archlinux rocketmouse]# downgrade ardour
Available packages:

   1) ardour-3.5.380-1-x86_64.pkg.tar.xz (remote)
   2) ardour-3.5.357-1-x86_64.pkg.tar.xz (remote)
   3) ardour-3.5.308-2-x86_64.pkg.tar.xz (remote)
   4) ardour-3.5.308-1-x86_64.pkg.tar.xz (remote)
   5) ardour-3.5.143-1-x86_64.pkg.tar.xz (remote)
   6) ardour-3.5.74-1-x86_64.pkg.tar.xz (remote)
   7) ardour-3.5.14-1-x86_64.pkg.tar.xz (remote)
   8) ardour-3.4-1-x86_64.pkg.tar.xz (remote)
   9) ardour-3.3-1-x86_64.pkg.tar.xz (remote)

[root at archlinux rocketmouse]# pacman -Syu
[snip]
warning: ardour: ignoring package upgrade (2.8.16-1 => 3.5.380-1)
[snip]

I want to test the current version of Ardour 3, but want to be able to
get back Ardour 2.

[root at archlinux rocketmouse]# ls -hAl /var/cache/pacman/pkg/ard*
ls: cannot access /var/cache/pacman/pkg/ard*: No such file or directory

Unlikely that people keep old cached packages for years.

Anyway, the OP could use downgrade to get linux 3.14 :).
