Check /etc/udev/50-udev.rules. You should have a line that says: KERNEL="agpgart", NAME="misc/%k", SYMLINK="%k" A quick explanation of how udev works may help you find the real problem here: For drivers compiled into the kernel, their device nodes get created either: 1. permanently by creating the device nodes manually and using the tarball feature in /etc/conf.d/rc 2. When udevstart is executed by /sbin/rc during startup For modules, the device nodes are created when the kernel runs /sbin/udevsend when the module is loaded. You *must* have hotplug support in the kernel for this though. You can cause udev to generate debug messages by setting "udev_log = 7" in /etc/udev/udev.conf. The debug output goes to /var/log/messages. >-genkernel --udev --menuconfig all will not show me an option that refers >to AGP anything, is this a bus? > > Well, in the normal kernel configuration, It is under "Device drivers->Character devices->/dev/apgart". You need both AGPGART and the chipset specific driver. For example, my config has: carcharias linux # grep AGP /usr/src/linux/.config CONFIG_AGP=y # CONFIG_AGP_ALI is not set # CONFIG_AGP_ATI is not set # CONFIG_AGP_AMD is not set # CONFIG_AGP_AMD64 is not set CONFIG_AGP_INTEL=y # CONFIG_AGP_NVIDIA is not set # CONFIG_AGP_SIS is not set # CONFIG_AGP_SWORKS is not set # CONFIG_AGP_VIA is not set # CONFIG_AGP_EFFICEON is not set >-I tried compiling the kernel directly once and got a kernel panic, I >don't remember if AGP was mentioned in that case. > > > Most common cause of this is not compiling the required drivers for your root filesystem (disk and filesystem drivers) into your kernel. Such drivers cannot be modules without a great deal of effort. -Richard -- gentoo-user@gentoo.org mailing list
