It maybe worth checking with one or more of the mainline kernels to see if these behave differently from the Ubuntu kernel just to see if they boot fine or if they suffer from the same issue.
The mainline kernels can be found in https://kernel.ubuntu.com/~kernel- ppa/mainline For example, it may be worth installing the initial 5.8 kernel release https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/ - use the following: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800_5.8.0-050800.202008022230_all.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-image-unsigned-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-modules-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb If this boots OK, then maybe then try the latest mainline 5.8 kernel in https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8.18/ Failing that, it may be worth trying the mainline kernels from 5.5..to 5.7 too to see when the issue starts to occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904054 Title: kernel 5.8 general protection fault at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
