Hi guys,

Since updating to 3.3.1 from 3.2.x my DVB-S2 tuner has stopped working 
and seems to block when accessed:

[ 6182.111792] pctv452e: I2C error -110; AA 0F  D0 03 00 -> AA 0F  D0 03 00.
[ 6182.419919] dvb-usb: error -110 while querying for an remote control 
event.
[ 6182.989972] dvb-usb: error -110 while querying for an remote control 
event.
[ 6184.170082] dvb-usb: bulk message failed: -110 (4/0)
[ 6184.185065] dvb-usb: error -110 while querying for an remote control 
event.
[ 6184.356753] dvb-usb: error -110 while querying for an remote control 
event.

The I2C errors were logged under 3.2 also but the card still worked.
Has anything substantanial changed? Can enable debug and/or ssh access 
if it would help diagnose the problem...

I also have a DM1105 based card that doesn't attach:

[ 1623.471563] DVB: registering new adapter (dm1105)

[ 1662.223235] dm1105 0000:00:0b.0: could not attach frontend

Any idea what I could do to find out whats wrong?

Thanks,
