#52013 — linux-image-4.3.0-1-686-pae unstable after 60 minutes

Since upgrade to linux-image-4.3.0-1-686-pae I experience unstable system
after 60 minutes.

I am using XFCE desktop and primary Iceweasel.
After about 60 minutes, oom-killer suddenly start to kill system, first
Iceweasel, then Xorg etc., taking down tasks so fast only solution is a
hard reboot.

If I boot up in linux-image-4.2.0-1-686-pae, all is stable again.

linux-image-4.2.0-1-686-pae 4.2.6-3 i386
linux-image-4.3.0-1-686-pae 4.3.3-2 i386

I have tried to setup atop to log memory every 10 seconds, but until now
not possible to identify what is causing oom-killer.

Wifi has something to do with this.
With linux-image-4.3.0-1-686-pae I see a few error messages from
wpa_supplicant, always within a minute before oom-killer start.

I have now removed my USB Wifi, computer is also on cable net, and problem
have gone away.

Which driver is used for wifi on this computer?
