Subject: Re: mix of ACPICA regression and EFISTUB regression (Was: kernel >=
 v6.2 no longer boots on Apple's Virtualization.framework (x86_64); likely to
 be related to ACPICA)

[Resending as a plain text email]

Turned out that this is a mixture of an ACPICA issue and an EFISTUB issue.

Kernel v6.2 can boot by reverting the *both* of the following two commits:
- 5c62d5aab8752e5ee7bfbe75ed6060db1c787f98 "ACPICA: Events: Support
fixed PCIe wake event"
- e346bebbd36b1576a3335331fed61bb48c6d8823 "efi: libstub: Always
enable initrd command line loader and bump version"

Kernel v6.3 can boot by just reverting e346bebb, as 5c62d5a has been
already reverted in 8e41e0a575664d26bb87e012c39435c4c3914ed9.
The situation is the same for v6.4-rc3 too.

Note that in my test I let Virtualization.framework directly load
bzImage without GRUB (akin to `qemu-system-x86_64 -kernel bzImage`).
Apparently, reverting e346bebb is not necessary for loading bzImage via GRUB.

Uploaded v6.1 dmesg in the bugzilla.
v6.2 dmesg can't be provided, as it hangs before printing something in
console=hvc0.
(IIUC, console=ttyS0 (RS-232C) is not implemented in Virtualization.framework.)
