The last update contained a new kernel, but the freeze still occurs.

$ uname -a
Linux lubuntu 3.11.0-6-generic #12-Ubuntu SMP Mon Sep 9 15:56:19 UTC
2013 x86_64 x86_64 x86_64 GNU/Linux

It can happen as seldom as once or twice a day but always entails losing
whatever I have worked on since last save (which usually isn't much).
Also in Lubuntu (LXDE) that also means losing window positions and
content.  As far as I can tell it happens any time but has happened
about 4 times when installing an app from the repository and 3 times
when shutting down for the day.  alt-sysrq-reisub has the effect
described above.
