Keith,

such information would be really handy as we have to write up some release
notes for the known bug for when 13.10 final-beta comes out on Thursday.

With the fix from upstream only currently available in amd64 for the 'it
freezes at the end of instal' section, which does not solve a further bug
that we can see. Joe is of the opinion that there are, in fact, two bugs
affecting zram. Getting the upstream patch into an ISO will at least give
ISO's that will install on lower RAM machines without the 'freeze' at the
end. It will also allow people with 32 bit, amd-mac and ppc architecture to
take it for a spin (excuse the pun).

Regards,

Phill.
