[Bug 1892290] Re: PXE load Focal initrd.img-5.4.0-42-generic always timeout

[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 2.06-2ubuntu3

---------------
grub2 (2.06-2ubuntu3) jammy; urgency=medium

  * Cherry-pick the missing hunk back that changes parameter loading
    in grub-core/loader/i386/linux.c, this should fix booting on
    BIOS systems.
  * Fix the fallback for kernel addresses on amd64 EFI, if the kernel
    could not be allocated at the preferred address, reset errno such
    that if the 2nd allocation succeeds, we do not fail erroneously.
