I consulted once for a hospital that was experience seemingly random network outages. After a few questions with the staff there it seemed to happen whenever a person stepped away from their windows (Lenovo) workstations for too long. Say, after lunch or breaks. After a wireshark of the network I determined it was a network card driver that was causing a broadcast flood on the network from multiple points for stations with the same driver version. While not the fault of Windows (I dont think anyways, as an update of the driver fixed the issue) your comment did remind me of this experience.
Bet the vendor made sure the drivers "worked" for suspend/resume, but only from the user point of view.
I may have just been lucky with Windows on my particular hardware. A quick search turns up a bunch of different problems. I think suspend/resume may just be a particularly difficult thing to get right.
