Comment 3 for bug 726796

I spent some time this AM giving this a closer look and one of the first things I tried was removing "quiet splash" from the kernel boot parameters thinking that may provide some clues, but doing so resulted in a successful boot. Restoring the "quiet splash" once again resulted in a failed boot.

Now, I've been fiddling with 'grub-customizer' for a few weeks:

Since I multi-boot, I next tried booting the new kernel using a different OS's grub and it succeeded every time. Then I purged grub-customizer, grub-pc and grub-common - and also rm -R'ed both /etc/grub.d and /boot/grub. After reinstalling grub-pc all seems fine.

That is I can no longer reproduce the failed boot so I can only assume that some custom mods I'd made to the grub 2 configuration broke things. Sorry for the false alarm.
