Comment 29 for bug 1397321

Thank you. I've experienced the x64 can be less compatible, more memory greedy and sometimes slower... that's why I stick with i686. I'll reconsider.

> However, just to clarify, were you able to boot into 3.18-rc7 once you install all three files?

Yesterday it showed the same error as I shot in comment #19 above. But, today I dug into the /etc/default/grub in the way I diff below. I wanted to get rid of "Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported." message as well as I wanted to make the non graphical boot permanent.

Both kernels, 3.18-rc7 and the latest one 3.13.0-40 from distribution now boot smoothly (just the disk passphrase is not requested in the blue xubuntu screen).

I have no idea why the "quiet splash" was preventing me from booting.
