H4x with phaseone P+ backs

[Stefan811]

We got us the latest Hasselblad upgrade option on the H4x series and shooting with brand new P40+ and P65+ digibacks.
What happens is that after a wile of shooting, sometimes quite fast, sometimes after 500 captures the camera/back hangs itself. Different errors occour on the screen of the H4x. From camera communication error, ERROR 112:0, restart camera, to digital back busy. It seems that the camera and the back get stuck in communication with eachother. But the Problem is we can't locate the source of the error. We had the same problems with different backs, cameras, batteries, lenses, latency, whatever. For me it seems that maybe phaseone and/or hassselblad didn't even try this setup and haven't a proper firmware written for this.
Anyone with the same problems or any ideas.....

I did a shoot today with the H4X and a P30+ digital back.  No problems.
Slow pace though, 4 hrs and 169 images.

I did a second shoot with the H4X today, 400+ images
I did also get one Restart Camera error, 1203 if I recall correctly.
There might be some room for firmware improvements...
