Hi,

this is actually not a bug in GRUB.

It is that the kernel denied to declare some memory as writable and
executable at the same time.

It is fixed in this commit:

http://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff;h=5e00841da0f8a9350827a73719ca04295dbb719f

So rebuilding next will fix it without updating GRUB.

Best,
-Michael
