The issue is not exhibited when the dock is not attached to the laptop. Most of the time, it fails to resume from a suspend-to-disk. The system hangs and logs are not flushed to disk so I don't have more details. But sometimes (maybe 1 out of 20 times), it manages to resume and there are double-freed irq errors, as shown in the following logs. As far as I am concerned, the laptop is running fine on resume, but maybe this can give a hint to where the issue causing the hang is. I'm Ccing linux-usb and linux-pci as I couldn't tell which subsystem is responsible.
