Desde a minha última reinicialização (e eu assumo desde a última atualização do kernel), o ubuntu trava após eu retornar de uma tela bloqueada. Estou executando o Ubuntu 17.04 com o 4.10.0-32-genérico e um Radeon RX 480 (sem driver de radeons). Os logs contêm primeiro

então muitos falharam em enviar mensagens como

Parece que um bug semelhante ocorreu em Como faço para reduzir o atraso antes de bloquear depois de pressionar o botão de bloqueio? mas lá foi o contrário: o atraso aparece quando o registro, não quando desbloqueio.
É muito demorado se eu tiver que esperar 5 minutos antes de poder desbloquear a tela. Isso ocorre com mais alguém? Existe uma solução para isso?
Eu tenho um problema parecido, apenas com uma Radeon RX 560: o computador fica pendurado por vários minutos ao acordar a tela ou até mesmo ao trocar o modo de vídeo. Estou usando o Ubuntu Xenial 16.04.
Para mim, a solução foi instalar o driver amdgpu-pro (em vez do amdgpu que veio com a instalação do ubuntu):
