[Lubuntu-qa] Lubuntu 13.10 beta

An update,

the kernel boots okay and when stressed with swap does not crash. The next
step will be to make an ISO with it in and see if it does, indeed, squish
the bug. The kernel team are on the case and we will be asked to help test
an ISO at some point in the (hopefully near) future.

Thanks everyone for the input and testing on this. Weird crashes leaving no
trace are the hardest to track down.

Regards,

Phill.
