I was booting the same Xenial based HVM guest on the same host (but this time running Bionic / Xen 4.9). This combination does not crash the domain when opening HPET. Though the check and code that would do it is still there. I also found a bug report against xenserver which I believe is based on the same Xen version as we have in Xenial (4.6.5): https://bugs.xenserver.org/browse/XSO-809?focusedCommentId=16484&page=com.atlassian.jira.plugin.system.issuetabpanels %3Acomment-tabpanel
This and the code say that the crash is done because HPET is set to use an unsupported interrupt method (edge/level). Since the Linux guest is the same in both cases, and also the test + crash code, either the hypervisor or maybe the seabios seem to use a different default. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-aws in Ubuntu. https://bugs.launchpad.net/bugs/1741409 Title: stress smoke test hang with dev test on AWS Xenial kernel Status in linux-aws package in Ubuntu: In Progress Bug description: The test will hang on dev STARTING, and get killed by the timeout setting.
