[Touch-packages] [Bug 1822118] Re: Kernel Panic while rebooting cloud instance
I still haven't been able to reproduce this. If you can reproduce this easily, maybe I can provide some kernels to be tested? I'll keep trying to reproduce here. I compared my VM settings to why is in the bug description, and I have the same config, except the region. I wouldn't think that would have an effect, but I'll look into it. -- 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/1822118 Title: Kernel Panic while rebooting cloud instance Status in linux-azure package in Ubuntu: In Progress Status in systemd package in Ubuntu: New Bug description: Description: In the event a particular Azure cloud instance is rebooted it's possible that it may never recover and the instance will break indefinitely.

[Touch-packages] [Bug 1822118] Re: Kernel Panic while rebooting cloud instance
@Joseph, so I can reproduce this hang/crash issue across a variety of instances. I can't get any info back on a console, so debugging this is not easy. -- 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/1822118 Title: Kernel Panic while rebooting cloud instance Status in linux-azure package in Ubuntu: Incomplete Status in systemd package in Ubuntu: New Bug description: Description: In the event a particular Azure cloud instance is rebooted it's possible that it may never recover and the instance will break indefinitely.
