First experience:
* suspend-to-disk on the train
* dock (for external display/keyboard) and resume
=> hard locked desktop (pointer visible, rest is black, no response from
keyboard or mouse); had to shutdown machine using physical on-off button; no
mention of intel-driver related stuff in system logs around that time

I'll report back with more experiences as they come in.
