Hi folks.
I use Fedora Rawhide and today's update came with the new kernel
5.7.0-0.rc0.git6.1.
As it turned out this kernel won't boot. Instead, I see the black
screen and some times see messages:
exit_boot() failed!
efi_main() failed!

The last working kernel is kernel-core-5.7.0-0.rc0.git2.1

I looked at the spec file and found out that the last bootable kernel
was related to the commit cad18da0afb1
(https://src.fedoraproject.org/rpms/kernel/c/9949db6070c6ca501d7235760ca8aba120db7448?branch=master),
and the first non-bootable kernel related to the commit a10c9c710f9e
(https://src.fedoraproject.org/rpms/kernel/c/0561e0bf0e459dd4b27a77670de838128b87bd0e?branch=master)

Of course, knowing these two commits, I made bisecting with the vanilla kernel:

Unfortunately, kernel bisecting not telling exactly which commit is blame.
In my bisecting a lot of skipping commits because of the unsuccessful builds:
ld: arch/x86/boot/compressed/pgtable_64.o:(.bss+0x0): multiple
definition of `__force_order';
arch/x86/boot/compressed/kaslr_64.o:(.bss+0x0): first defined here
make[2]: *** [arch/x86/boot/compressed/Makefile:120:

make[1]: *** [arch/x86/boot/Makefile:114:
arch/x86/boot/compressed/vmlinux] Error 2
make: *** [arch/x86/Makefile:283: bzImage] Error 2

Can anyone here help me with this issue?

Thanks.

I encountered the same issue as you:

exit_boot() failed!
efi_main() failed!

and the following patches are very suspicious:

x86/boot/compressed/64: Use LEA to initialize boot stack pointer
x86/boot/compressed/64: Use 32-bit (zero-extended) MOV for z_output_len
x86/boot/compressed/64: Remove .bss/.pgtable from bzImage
x86/boot/compressed: Remove .eh_frame section from bzImage

I am not sure if reverting these patches can help you.

Thanks,
Like Xu

Please try with the patches at
https://lore.kernel.org/linux-efi/20200409130434.6736-1-ardb@kernel.org/

In particular, patches 3 and 4. The first one is a fix for upstream
commit 3ee372ccce4d ("x86/boot/compressed/64: Remove .bss/.pgtable from bzImage")

Thanks, I can confirm that these patches solve the issue with unbootable kernel.
But, now after successful booting, I see another issue.
Kernel logs flooded with the error messages:

I think be better if I fill another bugreport in drm mailing list or
will be enough reply to this mailing list from here?

Glad that the booting problem got fixed.

Probably cc both the drm and amdgpu maintainers and change the subject
to be more specific.

Thanks.
