Best regards, Thomas I found my kernel config file in: board/arm/rpi/linux.config but the header says "do not edit this file". What's the recommended way to change kernel settings? Anyway CONFIG_VIDEOBUF_GEN doesn't exist at all. This is the Multimedia configuration: # Multimedia core support # CONFIG_MEDIA_CAMERA_SUPPORT=y CONFIG_MEDIA_ANALOG_TV_SUPPORT=y CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y # CONFIG_MEDIA_RADIO_SUPPORT is not set CONFIG_MEDIA_RC_SUPPORT=y # CONFIG_MEDIA_CONTROLLER is not set CONFIG_VIDEO_DEV=y CONFIG_VIDEO_V4L2=y # CONFIG_VIDEO_ADV_DEBUG is not set # CONFIG_VIDEO_FIXED_MINOR_RANGES is not set CONFIG_VIDEO_TUNER=y CONFIG_VIDEOBUF2_CORE=y CONFIG_VIDEOBUF2_MEMOPS=y CONFIG_VIDEOBUF2_VMALLOC=y # CONFIG_VIDEO_V4L2_INT_DEVICE is not set CONFIG_DVB_CORE=y CONFIG_DVB_NET=y # CONFIG_TTPCI_EEPROM is not set CONFIG_DVB_MAX_ADAPTERS=8 # CONFIG_DVB_DYNAMIC_MINORS is not set Mark
