As for freezing we discovered that since kernel 3.10.6 zram is broken
If you are seeing issues on kernels before that, then it is a separate bug.
As for the report back from 'sudo parted -l' it is still there in the
kernel. This is a separate bug as to the 'crash and burn' issue we have
You really do need to file a bug against this, as all kernel bugs have
different causes and whilst 'we' may think it is the same issue, only when
the kernel team have the finer details can they make that call.
from a terminal run: ubuntu-bug linux
Then add as much information as you can (It will send a lot of basic
information that they need).
