Oh I didn't realize Ubuntu 20.04 has a version of libc that's a little too old for that. You will need to try an older kernel version that's still newer than the 5.8.0 that caused this bug. Maybe try:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.56/amd64/ Also the "invalid signature" problem I think is caused by Secure Boot. Try disabling Secure Boot in your BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937321 Title: System freeze (amdgpu kernel crash on resume from suspend) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.8/+bug/1937321/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
