Is you select 4.4.0-15 from GRUB menu it boots, correct? We should be able to perform a kernel bisect to narrow down the commit that introduced this regression. We first need to identify the last good kernel version and the first bad one.
Can you test the following upstream kernels: 4.4.6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.6-wily/ 4.4.15: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.15/ 4.4.50: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.50/ ** Tags removed: kernel-key needs-bisect ** Tags added: performing-bisect -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742789 Title: Xen PV Guest won't boot latest kernel- OSError: [Errno 28] No space left on device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
