I have an exteral eSATA disk connected to a Lenovo L420 notebook, which I use only for data. The system (13.04, 3.8.0-29-generic) boots from the internal disk.
Now the system goes to standby while the external disk is mounted. Then I switch off the external disk.
When the system now resumes, and I forgot to switch on the external disk, resume fails permanently, even if I switch on the external disk and wait.
The system then needs to be force-stopped and restarted.
Isn't this behaviour unexpected? If the system cannot resume with the external disk basically missing, I'd expect it to wait until it becomes available, and then resume normally, instead of failing permanently.
