Hi,

iīm one of the others with the same problem with a new Nova (using the
budget-ci driver).
I have the same problem with both cards (TT budget & SS2) and i have done
some (very little) tests around this.

#1 The driver does not got to sleep....the frontend deliver the right
voltage value for the current polarisation, and the frontend driver seems to
tune as aspected (tunig with vdr and szap works). But, without delivering
usefull data...

#2 on my setup i can use the SS2 for around 2-3h for egp-scanning in vdr
before the card goes into an unusable state...the TT budget run up to 24h.

First i have think about an buggy stv0299 driver (my SS2 and TT budget share
the same driver), but tuning seems to work, so i now think the problem
caused by some of the dvb_core stuff, like the dmx or demux drivers, because
we have different card dependend drivers, and i donīt think the different
drivers will sharing the same "bugs". And remember, the FF cards go
sometimes in a same way mad on some setups....
