I narrowed down the cause of the hangs to normal.mod, from grub-2.02-beta2. With vanilla upstream source the same module seemed buggy, but instead of a hang, I got this: > qemu: fatal: Trying to execute code outside RAM or ROM at 0x9ef000e9
The good news is, dropping normal.mod from the grub-mkimage line (used to build d-i netboot images for non-Linux arches), I could get a rescue shell, and it looks like the PXE issue has been fixed in this version. I tried loading normal.mod via TFTP. I noticed it made requests for modules terminal and gettext as well. So I started over, adding those two additional modules to the grub-mkimage line. And now it works! It turns out those *are* listed in moddep.lst as dependencies of normal.mod, but grub-mkimage doesn't seem to compute the dependencies itself? This could be either a grub-mkimage bug or limitation, If it's the latter, grub-mkimage users need to beware of dependencies changing in new upstream GRUB versions. The symptom was simply a hang or reboot, not very helpful. I'll provide a patch for d-i shortly to at least work around it.
