I am using upstream EDK2 (https://github.com/tianocore/edk2) compiled in
debug mode

I can reproduce the bug with

qemu-system-aarch64 -M virt,gic-version=3 -cpu host -smp 4 -m 4G
-display none --enable-kvm -serial stdio \
-device
virtio-blk-pci,bus=pcie.0,scsi=off,drive=drv0,id=virtio-disk0,bootindex=1,werror=stop,rerror=stop
\
-drive
file=/home/augere/VM/IMAGES/aarch64-vm0-rhel-alt-7.6.qcow2,format=qcow2,if=none,cache=writethrough,id=drv0
\
-bios
/home/augere/UPSTREAM/edk2/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/FV/QEMU_EFI.fd
\
-net none -d guest_errors

also with virtio-blk-device

Thanks
