[linux-dvb] TT S-1500 CI not finding frontend driver

	Hi ,all
I have the following problem with a TT S-1500 CI.
It used to work with no problem (card+ci OK). At some point things went  
bad, namely either the cam is working (like in the following log) and  
the frontend does not attach with a i2c timeout, but sometimes it is  
the reverse, and finally unfrequently both work.
Is this a known problem, it does smell like an irq problem but I  
already tried different settings in the bios and even when it worked it  
did no last (eg the card works for a while and then quit working with  
no notice (with no power cycle in beetween).
Is it a hardware failure?
Thx for any help
Bye
Manu
