Comment 127 for bug 1311247

I successfully tested this patch.

Here is what I did :
- enabled proposed repository
- ran the following command-line (it might not be the same on different hardware) :
sudo apt-get install grub-pc
On my computer (no UEFI), it upgraded the following packages :
grub-common grub-pc grub-pc-bin grub2-common
- disabled proposed repository
- rebooted the computer (and pray ;-) ) : no error message
- rebooted the computer more than 20 more times (with some cold reboots, with and without displaying the grub menu, and after playing with memtest86, too) : no error message
- checked that the version displayed in the grub menu is 2.02~beta2-9ubuntu1.4

So I'd say it really fixed the issue for me, with no side effect.
I don't know what happened in bug 1507175 , but I did not have this issue.
I'm not sure if I should replace the verification-failed tag, but I'll add a verification-done one.
As grub is a very critical piece of software, I would be more confident if some other persons confirm it's working for them too.

NB : I'm using Ubuntu 14.04.3 (64bit) on an Asus Eee PC 1015PX
