Scanning DVB and crash do not seem to be related. It seems to crash in DirectFB, somewhere related to fusion (ie. multi-application core). Could you try to recompile DirectFB in single application core, and do not load the fusion kernel module.
PS : you may be better helped on the directfb-users mailing-list if it's really related to DirectFB...

Sorry my last mail is not quite good. This is correct mail.
Hello list!
Firstly I have to say this mail is very long cause I attached lot of information to be helped. My problem is that I have vdr running in my system Fedora Core 2 with kernel 2.6.10. I could see image from some days (two or three maximum) but it's not quite often. The system can't begin to take image unless it has a full-scan made when computer is powered on, but also it crashes lots of times before, so related with this problem I use a script to get all working.
My script consist in these lines:
#commands and lines used: DVBDIR="../DVB" VDRPRG00="export LD_ASSUME_KERNEL=2.4.1" VDRPRG01="export LANG=en.US" VDRPRG02="export LC_TYPE=POSIX" VDRPRG="./vdr -P softdevice -P 'remote -i /dev/input/event3' -P femon -P subtitles"
SCANCMD="../linuxtv-dvb-apps-1.1.0/util/scan/scan-all" LSMOD="`/sbin/lsmod | grep -n 'tda' | wc -l`" KILL="/usr/bin/killall -q -TERM"
# Load driver if it hasn't been loaded already: if [ $LSMOD -eq 0 ] ; then (./terrestrial.sh; modprobe fusion;"$SCANCMD") fi
PROB="`grep null /video/channels.conf|wc -l`"
n1=0
CHANLINES="`cat /video/channels.conf |wc -l`" #This is used to have a complete channels.conf to my config and not to be in a bug while ([ "$CHANLINES" -lt 10 ] && [ $n1 -lt 5 ] || [ "$PROB" -gt 0 ] && [ $n1 -lt 5 ]) do "$SCANCMD" CHANLINES="`wc -l /video/channels.conf|cut -c1-2`" PROB="`grep null /video/channels.conf|wc -l`" n1=`expr $n1 + 1` done
#Infinite bucle to have an scan in restart option and always vdr crushes and it could be "solved" while (true) do export LD_ASSUME_KERNEL=2.4.1 export LANG=en.US export LC_TYPE=POSIX ./vdr -P softdevice -P 'remote -i /dev/input/event3' -P femon -P subtitles if test $? -eq 1; then (echo "Making a scan"; "$SCANCMD") fi echo "Restarting VDR" done
When I execute this script I take:
-------------> ./script Inserting DVB modules into kernel saa7146: register extension 'dvb'. saa7146: register extension 'budget dvb'. saa7146: register extension 'budget_ci dvb'. saa7146: found saa7146 @ mem e2abee00 (revision 1, irq 5) (0x13c2,0x1011). DVB: registering new adapter (TT-Budget/WinTV-NOVA-T
PCI). tda1004x: Detected Philips TDA10045H. tda1004x: Detected Philips TD1316 tuner. DVB: registering frontend 0:0 (Philips TDA10045H)... TT-Budget/WinTV-NOVA-T PCI adapter 0 has MAC addr = 00:d0:5c:23:19:fc saa7146: register extension 'budget dvb /w video in'.
Then I make a full scan, cause if I don't do it, I can't get image in a long time or in a lot of crashes.
This is the result of making a full scan in my area; then channels.conf:

----------> And I can continue
If I make an ulimit -c unlimited to take core files and use gdb to solve the problem, but the only thing I get from debugging are results like 0xb7f0a31a, 0xb7fa2a26, 0xb7a6f097, 0x ffffe410...
