Hi
I checked out and build today the latest vl4-dvb drivers
(changeset: 10210:985ecd81d993) against the 2.6.27.1 kernel
and the drivers segfaults on load for me.
Attached is the segfault + /proc/interrupts output.
I have in my system both the hvr-1300 and hvr-4000.
Last driver version that I have tested to work is from 2008-12-31.
(changeset: 10165:3e5f56413191 which added the FE_CAN_2G_MODULATION
flag)
With this older version of driver I am able to tune to dvb-t (from
hvr-1300) and dvb-s/s2 (from hvr-4000) with command line tools like scan,
szap,szap2 or older vdr-1.6.0 which is not aware from s2api and uses thus
older dvb driver api.
But even with that version (2008-12-31) version of driver there is some
problem, because unlike the hvr-3200 users, I am not able to change dvb-s
or dvb-s2 channels with vdr-1.7.3. Changing of dvb-t channels works ok.
If I have earlier szapped the correct dvb-s/s2 channel by using the
szap/szap-s2 and then quitted it with ctrl-c and started vdr-1.7.3, I am
able to watch that S/S2 channels, but any attempt to switch for
some other s/s2 channels will fail. Unlike Gregoire Favre who is not able
to tune any S/S2 channels even from command line, I do not have diseqs
installed in my system. (hvr-4000 is connected directly via wire to lnb)
