All steps look right. `sudo apt reboot` won't work though, its either `reboot` or `systemctl reboot`.
After that you need to pick the correct kernel. You can do that during boot time, on Ubuntu its grub so maybe try `sudo update-grub`(I think, if not try grub-update). Then just pick the correct kernel version during the boot sequence, I think its in "advanced options" in grub menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950062 Title: Unable to access CPU i2c interfaces with AMD "Cezanne" CPU's To manage notifications about this bug go to: https://bugs.launchpad.net/amd/+bug/1950062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
