I can reproduce - here are the steps: I installed an HP m400 (mcdivitt) with wily, and installed qemu-efi (0~20150106.5c2d456b-2) and qemu-kvm (2.3+dfsg-5ubuntu9.1).
$ wget http://cloud-images.ubuntu.com/wily/current/wily-server-cloudimg-arm64-uefi1.img $ dd if=/dev/zero of=flash0.img bs=1M count=64 $ dd if=/usr/share/qemu-efi/QEMU_EFI.fd of=flash0.img conv=notrunc $ dd if=/dev/zero of=flash1.img bs=1M count=64 Then created my-seed.iso following instructions at http://ubuntu- smoser.blogspot.com/2013/02/using-ubuntu-cloud-images-without-cloud.html I then booted with: $ sudo qemu-system-aarch64 -enable-kvm -m 1024 -cpu host -smp 4 -M virt -nographic -pflash flash0.img -pflash flash1.img -drive if=none,file=wily-server-cloudimg-arm64-uefi1.img,id=hd0 -device virtio-blk-device,drive=hd0 -drive if=none,file=my-seed.img,id=hd1 -device virtio-blk-device,drive=hd1 -netdev type=tap,id=net0 -device virtio-net-device,netdev=net0,mac=ac:67:de:d2:4b:06 After logging in, my console would hang with "irq 37: nobody cared (try booting with the "irqpoll" option)". So I did so, and was able to login and type "sudo reboot". I then observed that it did not, in fact, reboot. ** Changed in: edk2 (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1527047 Title: arm64: wily: hanging during reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1527047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
