I forgot to mention that sometimes my system just blocks with a blinking cursor in the text console immediately. Once, using the "vbe-post" quirk to pm-hibernate, I went trough the complete suspend-resume cycle but then it blocks at end, right where it should bring back the system to life (I recognize it because, as it used to be in feisty, a white strip appears in the middle of the screen right before this moment). However, regarding the quirk, I think it has nothing to do and it all happened by chance, since I have "SAVE_VBE_STATE=true" in /etc/default/acpi-support, which I attach.
