Public bug reported:

After upgrading the memory from 8GB to 16GB I get randomly segmentation
faults of the X server. Tests with either set of 8GB works fine and a
memory test (memtest86+) ran for a week without any complaints. The
machine is a Lenovo Thinkpad W510 with an nVidia Quadro FX880M running
Maverick (10.10). I utilize the nVidia drivers that came with Ubuntu
although they are marked as Beta?! Basically the same problem exists on
my workstation that had from the go get 16GB but it runs Natty (11.04).
