[linux-dvb] budget-ci (Technotrend / current CVS) + irdeto 2.09 crash

["Denis Cheong" <denis@denisandyuki.net>]

I'm trying to get the new budget-ci code working on my Technotrend DVB-S
(stv0299 tuner) but I'm getting a segmentation fault when budget-ci.ko is
loaded.

System is Mandrake 10.0 with kernel 2.6.3-9mdk and a fresh CVS checkout
(budget-ci.c is revision 1.18).  Build was from the build-2.6 directory
using (i.e. outside the kernel tree).

The crash happens whether the Irdeto CAM is inserted or not.  I also have
a Hauppauge WinTV Nova-T in the machine (have tried not loading the
drivers for it but it doesn't seem to make any difference).

Everything is working perfectly with the DVB modules from the 2.6.3-9mdk
kernel (except of course the CAM).

The module load order I am using is as follows:

        echo "Inserting DVB modules into kernel"
        # make sure input stuff is there for IR remote controls
        modprobe evdev
        # vide4linux for av7110 based "full featured" cards
        modprobe videodev
        modprobe v4l1-compat
        modprobe v4l2-common
        modprobe video-buf
        modprobe i2c-core
        # DVB core
        insmod ./dvb-core.ko
        # frontend drivers
        insmod ./stv0299.ko
#       insmod ./tda1004x.ko
        # saa7146 based siemens/technotrend/hauppauge cards
        insmod ./saa7146.ko
        insmod ./saa7146_vv.ko
        insmod ./ttpci-eeprom.ko
        insmod ./budget-core.ko
#       insmod ./budget.ko
        insmod ./budget-ci.ko
