Meu Dell Precision 7510 com o Ubuntu 17.10 muitas vezes não consegue suspender. Mensagens de aviso são exibidas, então a tela de login volta.
dmesg dá:

Eu tentei uma solução deste site (não consigo encontrá-lo de volta) onde adicionei um script em /etc/pm/config.d/ com SUSPEND_MODULES=xhci_hcd , mas parece que não funciona.
