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.
- Run `LinuxVirtualMachine /tmp/bzImage /tmp/initrd.img`.
v6.1 successfully boots into the busybox shell.
v6.2 just hangs before printing something in the console.
## Tested versions
```
v6.1: OK
...
v6.1.0-rc2-00002-g60f2096b59bc (included in v6.2-rc1): OK
v6.1.0-rc2-00003-g5c62d5aab875 (included in v6.2-rc1): NG <-- This commit

```
Tested on MacBookPro 2020 (Intel(R) Core(TM) i7-1068NG7 CPU @ 2.30GHz) running
macOS 13.4.
The issue seems a regression in
[5c62d5aab8752e5ee7bfbe75ed6060db1c787f98](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5c62d5aab8752e5ee7bfbe75ed6060db1c787f98)
"ACPICA: Events: Support fixed PCIe wake event".
This commit was introduced in v6.2-rc1, and apparently reverted in v6.3
([8e41e0a575664d26bb87e012c39435c4c3914ed9](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8e41e0a575664d26bb87e012c39435c4c3914ed9)).
However, v6.3 and the latest v6.4-rc3 still don't boot.
