Hi all,
I was having a terrible problem OOM problem with kernel 4.4.76 and my CPU. However, it disappeared with kernel 4.4.77.
When I deleted the bottom panel, right-clicked on the desktop and added the "Default openSUSE Panel" the plasmashell invoked oom-killer: gfp_mask=0x14280ca(GFP_HIGHUSER_MOVABLE|__GFP_ZERO), nodemask=0, order=0, oom_score_adj=0
After several minutes dmesg showed that I was out of memory. Ref: https://bugzilla.opensuse.org/show_bug.cgi?id=1046500
This only happened with kernel 4.4.76x.
Will the final GA of 42.3 have kernel 4.4.77?
The kernel version difference might be a red herring.
If you're using an old Intel graphics chip, could you try to uninstall drm-kmp-default package once, reboot and retest?

I'm not sure what old Intel graphics relates to. I have an "Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz" and after updating to 42.3 from 42.2 I have frequent intermittent gpu hangs unless I boot with nomodeset. https://bugzilla.novell.com/show_bug.cgi?id=1050256
Unfortunately Intel tend to leave bugs for their old chips while developing for the newer chips. On Leap 42.3, we upgraded the kernel graphics stack to 4.9.x with a few backported fixes, but it seems problematic on some old chips. Luckily, we did upgrade via drm-kmp, so you can easily back to Leap 42.2 state just by uninstalling drm-kmp-* package. (This was the intention by providing via kmp, too.) So try to uninstall it and retest. If this fixes your problem, you can do "zypper al drm-kmp-default" not to install this any longer. We'll try to address the problem, but for old chips, the newer graphics stack has little merit, in anyway, so maybe it's not too bad to drop the PCI IDs of such chips from the supplement list...
