After a bit of wrestling with the arm64 ampere system, I was able to reproduce the outlined issues in this bug.
Console log is attached, the system will initially boot into the 5.11.0-27-realtime kernel, however, when a "reboot" command is issued, the host appears sit idle, and will not warm reset. On the console of helo-kernel, the system hang with step 3 with: [ OK ] Finished Reboot. [ OK ] Reached target Reboot. (no further update from this point) There are no other console logs that occur on the host -- 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/1946486 Title: Unable to reboot ARM64 node with 5.11.0-27-realtime Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in linux source package in Hirsute: Confirmed Bug description: It looks like this issue is affecting some ARM64 bare metal node: * helo-kernel 2 failed out of 2 attempts * kuzzle 11 failed out of 13 attempts (as far as I can recall 2 deployments failed early, the system was not deployed at all, so probably we can call it 9 failed) The boot test will fail, the system was unable to reboot with the 5.11.0-27-realtime kernel, here is the steps (integrated with the deployment script) 1. Deploy this node with Hirsute 2. Install the 5.11.0-27-realtime kernel and set to boot with this kernel by using the boot-kernel-simple in ckct. Reboot 3. System can boot with 5.11.0-27-realtime, reboot again to make sure it's OK It seem the system will stuck at the last reboot attempt in step 3.
