[linux-dvb] "Video datastream brocken" the legend continues ...

[Hermann Gausterer <mrq1@gmx.net>]

hi

(sorry for the new toplevel thread, i am new subscribed)

i have the scary problem with the "broken data stream" too ...
but my sitaution is even worse ... :-(

i am using kernel.org kernel-dvb 2.6.7, fedora core2, vdr -1.2.6, 
and as hardware 3 * dvb-s 1.3 on a dual p3-500 in smp

after testing the necessary modules, i`am using only i2c-core, videodev,
v4l1-compat, v4l2-common, video-buf dvb-core, ves1x93, saa7146, 
saa7146_vv, ttpci-eeprom, dvb-ttpci in that order, and it works at the
beginning very well ...

but after some time with epg-scan in the background, the recordings are 
broken and vdr restarts, this often happens many seconds after a recording 
is started, after a reload of all modules, it works again ..

problem 1) after some load/unload procedure, the module dvb-ttpci is 
always busy (of course without vdr running) and could`nt be removed
any more ... i have to reboot the system ... 

whats the cause of this? is there a way for getting info out of the kernel
what resource is busy or which process is using it (like fuser in usermode?)

problem 2) in the last two days my system is completly hardlocked
(system freez, even num-look-led does not react ... ) and this is very
bad ... i do not know how to get any debuging info out of an lock-up-kernel

this is very bad for me, in fact it is a showstopper for VDR ... :-((

my hardware worked "very" well with the old 2.4 kernel and the previos
drivers, only few corrupted recorings a week, never hardlocks or busy
modules here ...

i hope my info and possible assistance can help here :-)

as side-note, my syslog shows lot`s of debi & gpio interrupts, is this
"normal" or is there any additonal problem hidden here?
