Hi,
I've got a device connected with Pci-express to an mpc8641d_hpcn
evaluation board (rev. 2.0) and I'm using the latest kernel. This device
use MSI to generate an interrupt, but it seems possible that the only
MSI that can be triggered through the standard PCI Express is interrupt
0. Is there a way to solve it? Some workaround or something like it?
Thanks.

what exactly do you mean by using the latest kernel? The powerpc-next
tree or 2.6.26?

kernel 2.6.25.7, but I think it isn't a kernel problem but an hardware
problem instead, so I wondered if there's a patch for that problem.
