In that case please disregard those patches. Can you try this diff below
which will log any invalid accesses and see if anything appears on
stderr?

Title:
Qemu after v5.0.0 breaks macos guests
Status in QEMU:
New
Bug description:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than
the Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem,
whereas git tag v5.0.0 (or 4.2.1) does not, so something between
v5.0.0 release and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a
Xeon host:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu
Penryn,vendor=GenuineIntel,kvm=on,+sse3,+sse4.2,+aes,+xsave,+avx,+xsaveopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc
\
-device
isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
\
-smbios type=2 \
-drive if=pflash,format=raw,readonly,file="/tmp/OVMF_CODE.fd" \
-drive if=pflash,format=raw,file="/tmp/macos_catalina_VARS.fd" \
-vga qxl \
-device ich9-ahci,id=sata \
-drive id=ESP,if=none,format=raw,file=/tmp/ESP.img \
-device ide-hd,bus=sata.2,drive=ESP \
-drive id=InstallMedia,format=raw,if=none,file=/tmp/BaseSystem.img \
-device ide-hd,bus=sata.3,drive=InstallMedia \
-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-kbd -device usb-mouse
Perhaps something has changed in Penryn support recently, as that's
required for macos?

Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the
host when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work
fine - as does 5.5 kernel.
