Right - I should've mentioned that - the issue follows the guest kernel for me as well. I tested w/ latest upstream for both just in case the guest failure is a somehow a side-effect of a host kernel bug.
Also, I should have mentioned that this is an intermittent failure for me. I sometimes have to reboot the guest several times to observe the failure. The test also seems sensitive to changes in the test setup - for example, bumping up the guest cpu count to ~50 made the issue go into hiding. -- 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/1749040 Title: KPTI support for arm64 systems Status in linux package in Ubuntu: Incomplete Status in linux source package in Artful: In Progress Status in linux source package in Bionic: Incomplete Bug description: While regression testing the current linux-hwe proposed kernel (4.13.0-33.36~16.04.1), I found that it fails to boot on a Cavium ThunderX CRB.
