Follow-up Comment #7, bug #39460 (project grub):

I've just pushed several xnu patches which have fixed several xnu crashes. I
suppose this was one of them.

Was it really fixed? It would be helpful to know in which commit then.

I could reproduce some parts of this bug if trying to load 64-bit kernel ontop
of 32-bit EFI. Investigating.

Follow-up Comment #4, bug #39460 (project grub):

We both were attempting to use xnu loader on EFI which apparently does not
work (was it ever supposed to in the first place?)

I just retested with 2.02 beta2 using rescue CD which I explicitly restricted
to i386-pc platform only (so it boots in CSM). It boots OS X just fine on the
same MacBook I had issues before.

I'll post followup discussion on grub-devel.

Both photos show kp on the same hardware, a MacbookPro 4,1 (2008)
file #29720:  IMG_3403.JPG, this is xnu 12.3.0
file #28532:  IMG_20130710_16-2.jpg, this is xnu 12.5.0

Follow-up Comment #1, bug #39460 (project grub):

I think it should be considered to simplify the os x specific code in
os-prober and grub-mkconfig and instead chainload the Apple boot loader,
unless someone can think of really good reasons why a grub xnu specific
bootloader is necessary instead of the Apple one.

Details:

Release: grub2-efi-2.00-23.fc19.x86_64

To reproduce:
1. Updated to grub2-efi-2.00-23.fc19.x86_64
2. Clear NVRAM of all boot entries.
3. mount /dev/sda1 /boot/efi to mount the FAT32 ESP (instead of the default
Fedora hfs+ ESP)
4. grub2-install
5. grub2-mkconfig -o /boot/grub2/grub.cfg
6. reboot
7. At grub menu, choose OS X 64bit entry.

Actual results:
xnu kernel panics

Expected results:
Boots normally.

Regression:
chainloading the Apple bootloader allows xnu to boot normally without kp, as
does holding down the option key and choosing the firmware listed OS X volume
boot option. So it's definitely some issue with the xnu module.

Also, this doesn't work with any xnu 12.x or 11.x kernel (which goes back 1
and 2 years respectively). I'm not sure which version of xnu it does work
with.
