NVRM: GPU at 0000:01:00.0 has fallen off the bus. and Xorg Hangs, IRQ #16 disabled

The system worked fine with
kernel 3.9.6 + nvidia driver 319.23

Now i’m getting random hangs when playing civilizationVI under wine.
I tried those combinations without success:
linux-3.9.9 + nvidia 319.32
linux-3.10.9 + nvidia 325.15

What puzzles me is that, even 325.15 uses MSI, as you can see in the logs, the system complains about a bad irq, and disables IRQ #16 which was used by the nvidia card before 325.15

I also disabled my pata_jmicron controller which shared the irq 16 with the gpu, but the hangs remain.

Please, give me some advice…
