[Regression] since 12.04, GRUB can't see /boot located far from the start of the disk

[YannUbuntu]

1) Installed Ubuntu 11.10, no problem.
2) upgraded to 12.04. Result: the computer could not boot any more.
3) created a separate /boot partition at the start of the disk, then reinstalled GRUB in it. Result: the computer is now able to boot.

System informations about the system: http://paste.ubuntu.com/1103550/

The pc is not mine, i'm reporting the bug observed by another French user who can't use LP. Sorry I can't provide more information.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

The info you posted does not show a /boot partition, was it taken before you created one? Did you try reinstalling grub without creating a /boot parptition? What exactly does "could not boot any more" mean? What *did* happen?

Bug #916299 is probably a duplicate.
