Public bug reported: Hello!
I found that both of generic and snapdragon kernels from focal repository (5.4.0-14-generic and 5.4.0-14-snapdragon was tested) does not boot on Lenovo Yoga C630 WOS. Boot process hang at "Loading device tree blob..." (which means I can not provide apport report, because I can not boot kernel from focal repository, and apport refuse to collect information with other kernels). At the same time snapdragon kernel from https://kernel.ubuntu.com /~kernel-ppa/mainline/v5.4.20/ boot mostly fine (albeit with https://bugzilla.kernel.org/show_bug.cgi?id=204685 and https://bugs.launchpad.net/bugs/1863761 ). ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863939 Title: Linux 5.4.0-14 from focal repo does not boot on Lenovo Yoga C630 WOS, while Linux 5.4.0 from mainline PPA does boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
