I'm using Ubuntu 8.04 and kernel 2.6.24-21-generic. My card is Pinnacle 330e I've checked out em28xx-new and removed everything from /lib/modules/2.6.24-21-generic/kernel/drivers/media/video/em28xx. After make && make install I've rm'ed em28xx-audio and then modprobe'd em28xx-dvb and em28xx-aad. No /dev/aad0 was created so I tried to remove module em28xx-aad.Then following fault has occured:
