Behavior is the same after reverting to yakkety grub. This issue follows the guest kernel that we are rebooting *from*:
kernel running | kernel we | Reboot at reboot | reboot into | Success? -------------------------------------------- 4.10 | 4.10 | Failure 4.8 | 4.8 | Success 4.10 | 4.8 | Failure 4.8 | 4.10 | Success This suggests a bug in QEMU/qemu-efi. I suppose it could also be a bug in the kernel if it were a long-standing issue with boottime init that existed in 4.8 but was never tickled until now. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1675522 Title: arm64: Synchronous Exception at 0x00000000BBC129BC Status in edk2 package in Ubuntu: New Status in grub2 package in Ubuntu: New Status in linux package in Ubuntu: New Status in qemu package in Ubuntu: New Bug description: I installed a KVM VM with the zesty beta server ISO.
