When the system crashed, did you select to report the crash to
Microsoft?  If not, please do - those crash dumps will eventually find
their way to me, at which point I can analyze them in more detail to
figure out what's going wrong.

Does it still crash if you unplug the HCA from the switch (i.e. ports are down)?

Can you give some more details about your systems?  Your HCAs?

I don't know how that can be filled in, so right now that's left
blank.  In any case, the driver would need to be loaded to populate
this, so that wouldn't really help you.

At the moment, you unfortunately can't.  Unlike Linux, Windows doesn't
provide for a way to access PCI configuration space easilly from
user-mode.  So you need to have some sort of driver loaded - we're
working on a failsafe driver for when the HCA is in memory controller
mode, but that isn't ready yet.

So right now, you're left with having to do this from Linux.  That
said, I don't know if you'd have such old firmware that it would fail
- I suspect it's something else.
