This is a bit strange. I can't run X on the radoen PCI card if AGP is compiled, but X and the kernel is not supposed to use AGP in this case because it is a pci card! Seems very strange to me, particularly considering that 2.6.8.1 is able to run with both agp and drm. I've mounted /var synchronously so as to get the most of the crash log. It ends like this: (II) RADEON(0): Using 8 bits per RGB (8 bit DAC) (II) Loading sub module "int10" (II) LoadModule: "int10" (II) Reloading /usr/X11R6/lib/modules/linux/libint10.a (II) RADEON(0): initializing int10 (**) RADEON(0): Option "InitPrimary" "on" (II) Truncating PCI BIOS Length to 53248 A normal non-crashing run looks like this: (II) RADEON(0): Using 8 bits per RGB (8 bit DAC) (II) LoadModule: "int10" (II) Reloading /usr/X11R6/lib/modules/linux/libint10.a (II) RADEON(0): initializing int10 (**) RADEON(0): Option "InitPrimary" "on" (II) Truncating PCI BIOS Length to 53248 (--) RADEON(0): Chipset: "ATI Radeon 9200SE 5964 (AGP)" (ChipID = 0x5964) (--) RADEON(0): Linear framebuffer at 0xe0000000 (--) RADEON(0): VideoRAM: 131072 kByte (64 bit DDR SDRAM) (II) RADEON(0): PCI card detected (II) Loading sub module "ddc" (II) LoadModule: "ddc" (and so on) Another item that may be interesting: >>From the log, it looks like DRM failed to load for the PCI card when AGP wasn't present. Odd - it couldn't use AGP anyway. Maybe the explanation is that the xserver erroneously believes that it is an agp card? The log contains this: (--) Chipset ATI Radeon 9200SE 5964 (AGP) found It _is_ an "ATI Radeon 9200 SE", but it is definitely not an AGP card. I don't know wether the X server is mistaken, or if it merely is a wrong message. I don't think X should hang the kernel this way, even if it opens the AGP device by mistake. AGP is normally in use by the matrox card and should be unavailable anyway. Any further ideas?� More things to try? It'd be nice to get 3D on these newer kernels too. :-) I can post full logs if that's interesting. Helge Hafting
