Hi, could you film the boot process, especially for that error message shown in the top left corner and attach it here? Is it possible to access grub menu as I see you attached dmesg for -111 kernel, so I suppose you still retain the ability to select boot kernel. Then could you try following boot parameters and see if we have some more outputs?
initcall_debug debug log_buf_len=32M For detailed steps, please see https://wiki.ubuntu.com/Kernel/KernelBootParameters#Temporarily_Add_a_Kernel_Boot_Parameter_for_Testing . And when you rebooted into -111 kernel again, is it possible to run `journalctl -b -1 > journal.log`? Please have a check if it contains string "4.15.0-112". If so, could you also attach it here? ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888461 Title: After upgrade, Linux will not boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1888461/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
