No, I don't. The system simply stops working. Only the reset button
brings it back to life.

I've not measured the time, but I estimate it to be between 45 and
90 Minutes.

Sorry, I don't understand your question. Could you give me some advice,
how to test that?

Let me tell you, what I do:
I wrote a small script, that does the make insmod, tunes to the right
frequency and sets the appropriate multicast pid with dvbtune -n. After
that it does ifconfig dvb0_0 and starts a proxy, which is needed to
receive the data from "T-DSL via Sat".
I configured the script to be run when invoking the network runlevels,
to have sat-access in some kind of stand-by-mode in conjunction with
ISDN dial-on-demand.
So when the script is run from the runlevel the system stops working
after some time, even without having accessed the dvb0_0 interface. If I
do not run the script everything works fine.

If you have any hints, who I could investigate any further, please let
me know.
