Unfortunately, I stumbled on this same problem. What I see is that all but two Kernel configuration items are the same across multiple kernel versions. The two items that have changed are:
CONFIG_XEN_SELFBALLOONING=y (not sure why this has gone away) CONFIG_XEN_TMEM=m These two are missing in the 5.3.x kernels but XEN (Dom0) expects SELF_BALLOONING. I am limited in being able to experiment with this as most of my hardware is running Deb 9, 10 and Ubuntu 18.04. I have 19.10 running on a laptop that works with 5.0.0.xx and Xen. Hope this helps. In the meantime, when I get a chance, I'll poke around on the laptop for more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851091 Title: Fresh Eoan upgrade fails to boot dom0 with message "decoding failed" (kernel 5.3.0) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xen/+bug/1851091/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
