fsync: up and running.

Running Battlefield 4 I get the following series of syscall_fault warnings:

The message repeats endlessly, the game isn't crashing because of this immediately, I have no idea if this leads total freezes that I experience later on.

As it says "Exception" I would expect this to not happen.

Is __wine_syscall_dispatcher the function it tries to call or just an offset explanation for the where it calls in the dynamic linked library?
Any idea whats the issue here?
