It surely did, but I honestly don't remember what with. I'll try to bisect.

No Windows here, but see below

Well, it used to crash some industrial board (I believe it was some
Boser, HS-series, with
this card in a PCI slot of its backplane). So you're not alone in your
suspicions (OTOH,
that board was known to misbehave itself).

I have no particular need for that card, so if someone wants it for
testing I gladly
part with it (and if you happen be in Germany, I'll just mail it).
