--- Begin Message ---Package: linux-image-2.6.18-3-amd64 Version: 2.6.18-7 Severity: normal Hi all, yesterday I upgraded my amd64 machine from kernel 2.6.17-2 to 2.6.18-3. After compiling the Nvidia driver the X server produces the following error messages (happens with driver version 8776 and 9631) : (EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device PCI:1:0:0. (EE) NVIDIA(0): Please see the COMMON PROBLEMS section in the README for (EE) NVIDIA(0): additional information.(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device! (EE) NVIDIA(0): *** Aborting *** The kernel is sometimes showing this in syslog: titan kernel: NVRM: loading NVIDIA Linux x86_64 Kernel Module 1.0-9631 Thu Nov 9 17:35:27 PST 2006 titan kernel: NVRM: RmInitAdapter failed! (0x25:0xffffffff:1039) titan kernel: NVRM: rm_init_adapter(0) failed After some googleing I found a thread in a Gentoo forum saying that the IOMMU flag is set by default on the AMD64 kernels forcing the kernel agp driver to use instead of the nvagp from the Nvidia driver. The intermittent solution is to adjust the file arch/x86_64/Kconfig within the Linux source: replace this line... bool "IOMMU support" if EMBEDDED .... by ... bool "IOMMU support" .... and disable "IOMMU" in the kernel config. After compiling the kernel the Nvidia driver works like expected again.
