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
here are some info:
