Hi all,

Some progess on this issue, at last!

Quoting myself:

I sent a bug report to nvidia a little while back, and got an answer 
last Friday saying that with the newest drivers, they could only 
reproduce the problem about one in 5 times. I tried these new drivers 
(182.06+) and they do in fact seem to fix the problem almost completely. 
In my case, out of about 20 tries I could only reproduce the deadlock once.

So it's pretty clear it was a driver bug, and we got lucky that some 
other change also fixed our problem by side effect.

I've asked them to check the Linux drivers too.

For reference, if someone ever needs to send a driver bug report, I sent 
to (devsupport at nvidia dot com) and am quite happy with the turnaround 
time, considering I didn't have much hope of getting any answer at 
all... I didn't even need to be a "registered developer".
