Description Daniel Basabe 2008-03-08 12:10:28 UTC
Description of problem:

The last month I bought a new graphicscard for my computer.
It's a model Geforce 8400GS from Nvidia Corp.
The problem is when I want to use this hardware I can't.
The problem comes when the kernel  ( and olders) tries to map 
the pci i/o memory.

It prints:

PCI: Cannot allocate resource region 8 of bridge 0000:00:03.0
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.1
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.2
PCI: Cannot allocate resource region 8 of bridge 0000:00:03.3
PCI: Cannot allocate resource region 0 of device 0000:00:00.0
PCI: Cannot allocate resource region 3 of device 0000:02:00.0
PCI: Failed to allocate mem resource #3:2000000@de000000 for 0000:02:00.0

lspci -v:

You can try adding:


to the kernel boot options.

Comment 3 Chuck Ebbert 2008-03-10 22:12:49 UTC
The adapter wants a big chunk of contiguous memory and can't get it.

Comment 4 Daniel Basabe 2008-03-11 08:34:30 UTC
I solved this issue.

The problem was the bios of the motherboard, it was buggy.
I upgraded the bios to the newest. 
Now the iomemory maps are diferent and in the lspci -v  "Memory at <ignored>"
doesn't appear.

Thanks for yuor help!
