Hi @all, I have a Technisat Airstar 2 and gentoo with kernel 2.6.11.2 I'm having problems loading the modules for my Airstar. This is my kernel-config: Device Drivers --> Multimedia Devices --> <M> Video for Linux [...] DVB Devices --> [*] DVB For Linux [M] DVB Core Support [...] [M] B2C2/Technisat Air/Sky/CableStar 2 PCI doing make works without any problems doing make modules_install throws the following: WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/nxt2002.ko needs unknown symbol i2c_transfer WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/stv0299.ko needs unknown symbol i2c_transfer WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/mt352.ko needs unknown symbol i2c_transfer WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/mt312.ko needs unknown symbol i2c_transfer WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/b2c2/skystar2.ko needs unknown symbol i2c_del_adapter WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/b2c2/skystar2.ko needs unknown symbol i2c_add_adapter WARNING: /lib/modules/2.6.11.2/kernel/drivers/media/dvb/b2c2/skystar2.ko needs unknown symbol i2c_transfer Then, after booting the new kernel doing a modprobe dvb-core works perfectly, but doing a modprobe skystar2 throws the following: WARNING: Error inserting mt312 (/lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/mt312.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting nxt2002 (/lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/nxt2002.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting stv0299 (/lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/stv0299.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting mt352 (/lib/modules/2.6.11.2/kernel/drivers/media/dvb/frontends/mt352.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting skystar2 (/lib/modules/2.6.11.2/kernel/drivers/media/dvb/b2c2/skystar2.ko): Unknown symbol in module, or unknown parameter (see dmesg) And dmesg says this: [...] mt312: Unknown symbol i2c_transfer nxt2002: Unknown symbol i2c_transfer stv0299: Unknown symbol i2c_transfer mt352: Unknown symbol i2c_transfer skystar2: Unknown symbol mt352_attach skystar2: Unknown symbol stv0299_writereg skystar2: Unknown symbol i2c_del_adapter skystar2: Unknown symbol nxt2002_attach skystar2: Unknown symbol i2c_add_adapter skystar2: Unknown symbol i2c_transfer skystar2: Unknown symbol mt352_write skystar2: Unknown symbol stv0299_attach skystar2: Unknown symbol vp310_attach stv0299: Unknown symbol i2c_transfer Does anyone have an idea where the problem is? thx
