I'm pretty confident that 3.4.5 will work for you - I think it's the lack of
cylinder alignment that is causing trouble for you. You might want to read this
Ubuntu problem report:

Now there are multiple ways to fix this:

- Using any of the non-experimental builds will work for you.
- If you go for experimental builds, use the align-at option with a value that
  describes your cylinder size.
- setup-storage will have to take this into account more properly, but
  auto-detection will be almost impossible (it seems to be a BIOS issue), hence
  I'm currently favouring a align-at:cylinder variant of the "align-at" option.

Hope this helps,
