We did biscect this and found this commit (bb4aa6e06ee3877110a1dc0eb0d766ffac978993 in master) to be the first bad one. As gcc is mentioned in the commit message... We are building with gcc 13.1.1-1. Any idea what is going on here?Could you provide us more details? On which architecture/target do you run tests? Does GRUB start? If yes which kernel version do you try to boot? Could you send us a link to the GRUB and kernel packages and sources? Etc... Daniel
Hi,Tests have been ran on a x86_64 laptop (but the issue has been reproduced on several other x86_64 machines). GRUB does not start, we don't even reach the GRUB menu, nothing more than a black screen at boot. The kernel we're trying to boot is `linux 6.3.7-arch1-1` [1] (package [2]), but I doubt the kernel itself is in cause as we're able to boot it with a GRUB package built without the bb4aa6e06ee3877110a1dc0eb0d766ffac978993 commit. Here's a working GRUB package [3] and a faulty one [4].
Sources are taken from https://git.savannah.gnu.org/git/grub.git [5]. I remain available if you need specific tests or additional information.
