Sounds a bit strange to me, but nice if it helps for you...
I have a 9500S-12 and the latest firmware is 2.08.00.009 - which is flashed
on my controller already.

That's right, 2.6.16 on 3.0.4 works very well. I wouldn't call
it "solution", but it's a nice workarround, until someone cute fixes this
problem.
