Game freezes ( NMI watchdog: BUG: soft lockup - CPU#5 stuck for 23s! )

[Cursarion]

Soo, I installed Steam OS a few days ago and I've had a few freezes and crashes. Relevant:

Message from syslogd@steamos at Jun 18 16:04:44 ...
 kernel:[ 2729.749751] NMI watchdog: BUG: soft lockup - CPU#5 stuck for 23s! [csgo_linux64:2304]

This probably is a Steam OS issue? Because it's also happened on other game, not only CS:GO.

Syslog has stuff like this:

and .xsession-errors has a lots of these lines:

Hmm, did I put this in the wrong subforum...

I used to get freezes running an APU (A10-7800, plus a dedicated GPU, GTX 660), especially when I played Serious Sam 3. It was pretty random stuff, but that game was guaranteed to lock it up.

Others have had better success with stronger APU/GPU combos, and SteamOS is certainly changed now from when I was running it.
