Similar thing in my situation - all kernel including linux- image-4.13.0-25-generic work OK on my Asus Zenbook UX305FA but linux- image-4.13.0-26-generic makes my laptop almost unusable (everything is many times slower) and any newer version up to current linux- image-4.13.0-30-generic hang during start. On plymounth screen it boots up to progress bar and hangs just before showing mouse pointer (comparing to normal boot).
On the other hand all kernels from mainline PPA work without problem (including latest 4.14.13 and 4.15-RC8). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742675 Title: after upgrade to linux-image-extra-4.13.0-26-generic the system does not start at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
