Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> Linux kernel >= v6.2 no longer boots on Apple's Virtualization.framework (x86_64).
> 
> It is reported that the issue is not reproducible on ARM64: https://github.com/lima-vm/lima/issues/1577#issuecomment-1561577694
> 
> 
> ## Reproduction
> - Checkout the kernel repo, and run `make defconfig bzImage`.
> 
> - Create an initrd (see the attached `initrd-example.txt`)
> 
> - Transfer the bzImage and initrd to an Intel Mac.
> 
> - On Mac, download `RunningLinuxInAVirtualMachine.zip` from https://developer.apple.com/documentation/virtualization/running_linux_in_a_virtual_machine , and build the `LinuxVirtualMachine` binary with Xcode.
>   Building this binary with Xcode requires logging in to Apple.
>   If you do not like logging in, a third party equivalent such as https://github.com/Code-Hex/vz/blob/v3.0.6/example/linux/main.go can be used.

See bugzilla for the full thread.

Interestingly, this regression still occurs despite the culprit is
reverted in 8e41e0a575664d ("Revert "ACPICA: Events: Support fixed
PCIe wake event""), so this (obviously) isn't wake-on-lan regression,
but rather early boot one.

Also, the reporter can't provide dmesg log (forget to attach serial
console?).

Anyway, I'm adding it to regzbot:

#regzbot introduced: 5c62d5aab8752e https://bugzilla.kernel.org/show_bug.cgi?id=217485
#regzbot title: Linux v6.2+ (x86_64) no longer boots on Apple's Virtualization framework (ACPICA issue)

Thanks.
