description |
SRU Justification
[Impact]
At present, if a virt instance is hibernated and restarted in a different environment, the instance will crash. We have seen situations where customers have to enable support cases to recover an instance. The proposed patch is supposed to enable the kernel to detect the change and reboot the instance instead of crashing. In the ACPI specification; there is a 'hardware signature' field in the ACPI tables, and the OS can reboot cleanly if/when that signature changes, instead of attempting the resume and crashing.
[Fix]
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=74d95555
https://lore.kernel.org/lkml/9099d8903e9b2b16daec712acc9aa533fe84d102.camel@infradead.org/T/#u
[Test Case]
Hibernate an AWS instance, resume on a different platform.
[Where things could go wrong]
Resume currently crashes when a hibernated instance is migrated to a new machine. It can't get much worse, unless the initial hibernate fails.
[Other Info]
