I was posting some patches on the Nouveau mailing list in order to fix this issue. I also wanted some PCI folks to look at it, but nobody replied yet...
I am sure that this is in no way a driver issue, but an issue within the PCI subsystem or the PCIe controller, so we are kind of reluctant to push such a "workaround" into a driver as other devices might run into such issues as well? Or maybe it's some Nvidia hardware screwup? Anyways, I have not enough knowledge about how all that PCI stuff works, so I can't come to a final conclusion here.
