Hello
I encountered the same problem on my Notebook with the MCP67M chipset from
nvidia that arne had (2.6.20 works, later not). I think it is a different bug,
but I couldn't find it anywhere else...
I used the ahci driver in the meantime but had several other caveats.
This thread put me on the right track.
I'm using the gentoo-sources by now. 2.6.20 worked flawless, later kernels
didn't detect the nvidia sata chipset.
what I did was the following:
I compared the file drivers/ata/nvidia.c between the 2.6.20 and the 2.6.23
version (both with the gentoo chipset, but I didn't had any luck with the git
or vanilla sources)
I found following difference to mention:
2.6.20:
static const struct pci_device_id nv_pci_tbl[] = {
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE2S_SATA), NFORCE2 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE3S_SATA), NFORCE3 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE3S_SATA2), NFORCE3 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_CK804_SATA), CK804 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_CK804_SATA2), CK804
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP04_SATA), CK804 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP04_SATA2), CK804
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP51_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP51_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP55_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP55_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA3), GENERIC
},
{ PCI_VENDOR_ID_NVIDIA, PCI_ANY_ID,
PCI_ANY_ID, PCI_ANY_ID,
PCI_CLASS_STORAGE_IDE<<8, 0xffff00, GENERIC },
{ PCI_VENDOR_ID_NVIDIA, PCI_ANY_ID,
PCI_ANY_ID, PCI_ANY_ID,
PCI_CLASS_STORAGE_RAID<<8, 0xffff00, GENERIC },
{ } /* terminate list */
And 2.6.23:
/* static const struct pci_device_id nv_pci_tbl[] = {
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE2S_SATA), NFORCE2 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE3S_SATA), NFORCE3 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE3S_SATA2), NFORCE3 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_CK804_SATA), CK804 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_CK804_SATA2), CK804
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP04_SATA), CK804 },
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP04_SATA2), CK804
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP51_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP51_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP55_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP55_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA2), GENERIC
},
{ PCI_VDEVICE(NVIDIA, PCI_DEVICE_ID_NVIDIA_NFORCE_MCP61_SATA3), GENERIC
},
{ } /*terminate list */
I simply copied the old version (from 2.6.20) to the newer kernel (2.6.23)
compiled the kernel and TADA it worked.
As I don't have any programming scills, please correct me. But as fas as I can
see the MCP67M is simply not mentioned any longer (I think this
PCI_VENDOR_ID_NVIDIA, PCI_ANY_ID did the trick) but the source itself is
working. I think the MCP67M just has to be added to the list of hardware (I
don't know in the sata_nv.c or the in the pci_ids.h (is there the definition?)
Please tell me if I'm on the right track, as this kind of fiddling around is
completely new to me (even my first bugzilla entry).
