+
+qemu-system-aarch64: /build/qemu/src/qemu-2.12.0/block.c:3375: bdrv_close_all: Assertion `QTAILQ_EMPTY(&all_bdrv_states)' failed.
+
+
+
+This bug is present also on AARCH32, ARMv7 architectures
+
+
+Can you provide the various image files and so on somewhere so that I can reproduce, please? (My aarch64 test image shuts down cleanly, so it may be something specific to the guest you're using.)
+
+
+QEMU_EFI.fd:
+http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/latest/QEMU-AARCH64/RELEASE_GCC5/QEMU_EFI.fd
+
+sd-image:
+generated as this says:
+https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3
+(same error also with latest raspbian image)
+
+kernel image:
+https://github.com/M0Rf30/qemu-kernels-rpi-arch-arm/tree/master/rpi3
+
+initrd image:
+is indifferent. in cmdline is used the initrd from arch boot partition
+
+on releases previous to 2.12 this error is not present
+
+
+
+Could you just provide the files for the sd card and the initrd, please. I don't want to spend a bunch of time trying to recreate them when you already have them...
+
+
+In order not to upload a big image I can say that you can generate the image with this tool
+https://github.com/M0Rf30/simonpi
+the initrd used is in the arch linux arm boot partition generated by the previous referenced tool.
+
+
+As I said, I don't want to have to deal with image generation tools and extracting initrds from disk images. The easiest thing for me is if you can just provide all the files and the command line I can use to reproduce.
+
+
+https://mega.nz/#!M15RiY5S!7CvVemQAOQnxTcdcRnLNGqxlH6SAeL3oit_uWCs-yck
+here the sd image
+
+You can reproduce the bug without any Linux image.
+
+you can quit Qemu (CTRL-A C quit) without the bug reported
+qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -net none -parallel none -bios QEMU_EFI.fd
+
+
+or generate the bug with:
+qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -net none -parallel none -bios QEMU_EFI.fd  -hda fat:rw:aarch64/virtual_disk
+
+Get into the EFI shell and exit Qemu.
+The virtual_disk directory is empty.
+
+Thanks for the repro instructions. I think this bug was fixed by commit 41b6513436d2ebb64c7d, which should be in QEMU version 3.0 or later.
+
+
+PS: if you can still reproduce with current QEMU please do let me know and I'll reopen the bug and investigate further.
