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 (2.6.24.3-12.fc8 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: 02:00.0 VGA compatible controller: nVidia Corporation GeForce 8400 GS (rev a1) (prog-if 00 [VGA controller]) Flags: bus master, fast devsel, latency 0, IRQ 24 Memory at dd000000 (32-bit, non-prefetchable) [size=16M] Memory at b0000000 (64-bit, prefetchable) [size=256M] Memory at <ignored> (64-bit, non-prefetchable) I/O ports at 9f00 [size=128] [virtual] Expansion ROM at c0000000 [disabled] [size=128K] Capabilities: [60] Power Management version 2 Capabilities: [68] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [78] Express Endpoint, MSI 00 Xorg.0.log: (WW) ****INVALID MEM ALLOCATION**** b: 0xce000000 e: 0xce000000 correcting^G I attach more information of my system. Version-Release number of selected component (if applicable): How reproducible: Always. Steps to Reproduce: 1.Start the system 2. 3. Actual results: I can to use X whith the generic driver nv, but nvidia driver doesn't access to the hardware. Expected results: I hope that my hardware works fine. Additional info: See the attachment.

You can try adding: pci=bios to the kernel boot options.
The adapter wants a big chunk of contiguous memory and can't get it.
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!
