In the case you ran into amdgpu related freezes, try: amdgpu.audio=0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772081 Title: HP x360 - Ryzen 2500U Locks up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1772081/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
