Comment 24 for bug 996454

this is still an annoying issue on Precise, Trusty & Utopic at least. Its a show stopper bug for all the users without a third system or distro as he can't search for a possible workaround.

If you get into trouble for booting, then at least the recovery mode have to be bug free as possible. Letting such issue without assigning it is not a taste of serious distro.
