Does this exception happen very early in the boot, like before any other output by GRUB? I ask this because, if valid, this should ideally have been caught by the CI.

My working workaround for now is adding mem=4G to kernel commandline. Any value higher than 4G does not work at the moment. So seems definitly more a qemu issue and grub is not to blame here.
