I downloaded the following packages: linux-image-unsigned-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb linux-modules-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb
And installed them with sudo dpkg -i linux-image- unsigned-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb linux- modules-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb While trying to boot it, it stopped after "Loading initial ramdisk...". It didn't respond to keys in any way. I read that proprietary drivers (nvidia) could cause problems, so I selected Nouveau instead of nvidia from "Software & updates" -> "Additional drivers". This removed the nvidia-driver-460 package. Then I reinstalled the mainline kernel. But still it wouldn't go any further in the boot. (Kernels 5.4.0-89 and 5.11.0-36 still booted.) Am I doing something wrong or is the problem in the kernel? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953223 Title: USB device is not detected during boot, again To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1953223/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
