Hi, I seem to have hit this same bug with linux-image-generic-lts-raring
3.8.0-30.44~precise1 in Precise.
Was this fix applied in the 3.8 kernel in the Raring stack in 12.04.3LTS ?

Installed the new kernel from -proposed, I finally managed to alter EFI
vars. I tried bootorder, bootnext, disabling entry. It works!

Max, Phillip already explained that we can't help you here with your
problem. This bug specifically regards a flaw in how the kernel was
writing NVRAM variables for UEFI boot loaders. It is unrelated to GRUB.

I backported commit 31ff2f2 and built a Raring test kernel. This
backport also required upstream commits: 6b59e36, 0635eb8 and cc5a080c.
The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1173423
Can you test that kernel and report back if it has the bug or not?
I'll backport commit 31ff2f2, build a test kernel and post a link to it
shortly.
