Can you provide a new dmesg output from 4.18 kernel since you discovered you are able to boot on recovery mode? Just dump it somewhere so you can recover it once booted graphically with another kernel.
Basically once you are in front of the recovery screen, select the option to enable network, not because of network but because it's known to also mount filesystems in write mode, then select the option to open a root console, then type that: dmesg > /var/log/dmesg.$(uname -r) It will produce a file named like /var/log/dmesg.4.18.0-14-generic Then reboot on a non-faulty kernel and attach this file there, you can delete it from your computer after that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813657 Title: 4.18.0-14 doesn't boot past grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
