This also affects the mainline kernel build 4.17.0-041700.201806041953 that I was testing for another bug.
I've attached a photo of the screen with the issue occurring, in that version. Booting not under Xen seems to work around the issue, and the system comes up, but that's not useful for me because I need Xen. ** Attachment added: "Screenshot of the null pointer dereference message" https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1777338/+attachment/5153715/+files/Screenshot.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777338 Title: Linux 4.15.0-23 crashes during the boot process with a "Unable to handle kernel NULL pointer dereference" message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1777338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
