Usando um Chromebook da Toshiba, com o Ubuntu 16.04 instalado, tudo está bem até eu fechar a tampa para colocá-lo no modo de suspensão. Uma vez que eu abro a tampa, isso acontece no log de inicialização

O erro em questão é claro
Jun 06 18:40:16 kernel: ehci-pci 0000:00:1d.0: port 1 resume error -19
Logo após a conclusão do rastreio, o log do grub é preenchido com o erro, ocasionalmente imprimindo algo como "connect bounce failed" antes de alternar para
Jun 06 18:40:16 kernel: ehci-pci 0000:00:1d.0: port 2 resume error -19
Depois de alguns segundos, volte para a "porta 1".
Eu simplesmente não sei o que fazer com isso ou o que está causando o problema.
Além disso, o computador é muito lento para desligar, não sei se está relacionado ou não.
