I got absolutely the same panic as on the screen shot in comment #1 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1730188/comments/1). It caused by missing /boot/initrd.img-4.4.0-98-generic.
The problem was, that the /boot filesystem was almost full. I've removed all of the old kernels with the exception of the last 2 ones (.97 and .98), e.g.: sudo dpkg --purge linux-image-4.4.0-96-generic linux-image- extra-4.4.0-96-generic After that I've created the image file: sudo update-initramfs -c -k 4.4.0-98-generic sudo update-grub After that everything worked fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730188 Title: linux-image-4.4.0-98 kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1730188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
