Log message is: qemu log: EFI stub: Decompressing Linux Kernel... EFI stub: EFI_RNG_PROTOCOL unavailable EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path EFI stub: Exiting boot services ... and then there is nothing until I abort the emulation. Reverting this patch results in a build failure, so I awas not able to test it. Bisect results are atatched for reference.
