Hi all...

   I'm experimenting PCI  address space collisions on an ICOP PC104
VDX-6357 motherboard (with no cards/expansion at all) and kernels
2.6.33/34

collisions where not there with kernel 2.6.29 (I start with this
.config and I've done a make oldconfig for 2.6.33/34).

I have no ACPI support and I'm using the sisfb framebuffer on a XGI
Technology Inc. (eXtreme Graphics Innovation) Volari Z7 chipset.

thanks for any ideas

                   Paolo
