Oh, I see! I had no idea that error was related to secure boot. Thanks! I'll try that later and get back to you.
The drm-tip download page ( https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/current/ ) links to the following wiki pages, neither of which mention secure boot in any way. * https://wiki.ubuntu.com/Kernel/MainlineBuilds * https://wiki.ubuntu.com/Kernel/FAQ Maybe most folks who decide to install one of these kernels have enough background knowledge to figure this out; but if users are being invited to install these kernels as part of diagnosing bugs maybe it's worth adding a note to one of those pages about secure boot? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877889 Title: Intermittent hangs on boot Ubuntu 20.04 on Lenovo E595 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1877889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
