Trying to isolate the issue, I: 1. Booted my portable Ubuntu 18.04.6 installation on a different machine (different CPU, chipset, but still Intel). On the other machine, kernel 4.15.0-177 booted without issues, so apparently it does not depend on the installation, but rather on the hardware or BIOS whether the freeze occurs or not.
2. Replaced the entire /lib/modules/4.15.0-177-generic/ with the contents from /lib/modules/4.15.0-176-generic/ and rebuilt initramfs. This did NOT cure the freezes (only caused a lot of module signature errors, confirming that the modules really were replaced). So whatever is causing the freezes is not in one of loadable modules, but rather within the kernel itself or the builtin modules. Still, the 176-to-177 diff over the builtin modules is HUGE... :-/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1973167 Title: linux-image-4.15.0-177-generic freezes on the welcome screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1973167/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
