I don't know how to get a trace like you did. Nor do I understand anything 
in that link. Something in intel drm is fixed :-) I don't know which 
package that is. I suppose we will be getting it soon?

However, I did upgrade the laptop. Very strange! It is much older than the 
desktop.

Desktop has INTEL X3000 (Chipset 965G) graphics. It will not run KDE 
desktop effects with kernel 3.14.2, but will with kernel 3.13.10 and 
earlier. There are no mce errors.

Laptop has INTEL (Mobile 915GM/GMS/910GML Express) graphics. It will run 
KDE desktop effects with kernel 3.14.2 and there have been no mce errors 
yet, after 10 minutes (I don't know what triggers them). With the previous 
3.13 kernels, desktops effects also worked fine, but I was getting mce 
errors, even though there did not appear to be any indication of a 
malfunction. There was no /var/log/mcelog and running mcelog>output 
produced only an empty file. Go figure.
