The error is this: media_build/v4l/au8522_dig.c:748: error: redefinition of 'au8522_attach' media_build/v4l/au8522.h:69: note: previous definition of 'au8522_attach' was here make[3]: *** [media_build/v4l/au8522_dig.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [_module_media_build/v4l] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-2.6.32-45-generic-pae' In the bad .config file the modules: CONFIG_DVB_AU8522_DTV=m CONFIG_DVB_AU8522_V4L=m are enabled, but the main option: CONFIG_DVB_AU8522=m is missing! Adding it manually fixes the problem. I really have no idea about the origin of the problem, but I'm sure that a few months ago everything was working properly.
