I had a crash with a stack trace that looks VERY similar, but this was
on Arch Linux with kernel 3.12.6, with very different hardware. I am
running firefox with the .mozilla folder in ecryptfs on an ext4 hard
disk, and the crash happened while I was using firefox. Is that what you
are doing as well?

The strange thing is, I have been doing the same for months on a
different computer with no issues (also with kernel 3.11).
