This is a general problem when running any raspi kernel in ADT since the raspi kernels don't support ACPI. Software configuration seems to be different across different arm64 host HW in the ADT OpenStack cloud. Older HW has older qemu-efi installed which presents both ACPI *and* a DT to the guest and the raspi kernel boots fine in VMs running on such host HW. Newer host HW has newer qemu-efi installed which only presents ACPI and VMs running on such host HW fail to boot with the raspi kernel, leading to the above error/timeout.
The solution is to support a special ADT trigger 'qemu-eif-noacpi/0' which calls a script during testbed setup that injects a startup.nsh script into the EFI partition of the VM and changes NextBoot to the EFI shell. The VM then reboots after testbed setup, executes startup.nsh which sets a hidden EFI variable to instruct QEMU to present a DT and finally resets the VM for this change to take effect. When the VM comes back, the guest OS is presented with a DT and the raspi kernel boots and the test continues. That's the theory. However, the reboot method after testbed setup was recently changed for some reason. It now uses 'openstack reboot --hard' which results in a libvirt domain destroy and recreate which in turn results in loosing the EFI variable setting so the VM comes back with ACPI again and no DT. And the raspi kernel no longer boots... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1930082 Title: systemd/247.3-3ubuntu3 ADT test failure with linux-raspi H/G/F Status in linux-raspi package in Ubuntu: Won't Fix Status in systemd package in Ubuntu: Invalid Bug description: This is a scripted bug report about ADT failures while running systemd tests for linux-raspi/5.11.0-1009.10 on hirsute.
