@b-9 There may be various options, depending on how comfortable you are with the command line. You could try to build a custom initramfs image with diagnostic tools, boot from it and dump the necessary info to a USB drive for example. Or clone the ubuntu kernel git repository and use git bisect to pinpoint the commit that introduced the issue.
Definitely easier: boot your most recent working kernel normally and dump the requested information (lspci, dmesg etc.). Though the kernel version will not match exactly the information may help narrow down the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894378 Title: Cannot boot after updating kernel to version 5.4.0-45 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894378/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
