 linux 3.17.4-1
 linux-rt 3.14.25_rt22-1
 linux-rt-lts 3.10.58_rt62-2
 
 No problems with 3.17.4 and all versions 3.17.4 here, with one
 exception, building modules for the outdated virtualbox version 4.3.12
 still works for kernels = 3.16 (with and without rt patch), but
 doesn't work for 3.17 kernels. Building the virtualbox modules for
 kernels 3.17 works for current version of virtualbox, unfortunately USB
 is broken for all versions of virtualbox  4.3.12. A while ago rt
 kernels  3.8.13-rt locked my AMD machine, but that doesn't happen
 any more, e.g. the above listed linux-rt are ok, at least for
 non-audio work, I didn't used them for audio.

From what I've read, this is a particularly uncooperative bug in that it's not
only random but doesn't appear on all machine architectures.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

However, some distros for good reasons provide LTS kernels, for Arch
Linux it is

$ pacman -Si linux-lts | grep Version
Version: 3.14.25-1
