Hi All,

Further to Bob's email below, I confirm that this regression is
present in 2.6.30.2.

Once the problem occurs, I see the following message repeatedly in my logs:

Jul 27 21:49:21 f kernel: [ 2990.204264] dvb-usb: bulk message failed:
-110 (1/0)

>From what I can see, the problem can be remedied with a cold boot, at
least sometimes.
However, after running for a while, the problem reoccurs.   More
particularly, the card seems to work for a while when the device is
found in a 'cold' state.

With that in mind, I (naively) altered dvb-usb-init.c to try to load
firmware regardless of whether the device was cold or warm.   I also
tried increasing the timeout passed to usb_bulk_msg in dvb_usb_urb.c.
Neither approach made the card work reliably.

Would somebody more experienced than me please suggest a helpful
location for a printk or some other way to instrument this part of the
code to track down the problem?

Thanks!

Actually, that's not quite accurate - with the 2.6.27 drivers and
scandvb's channels.conf file, mythtv still can't tune the second tuner.
So as a nasty workaround, on every boot (in /etc/rc.local) I need to
use tzap to tune both tuners to _something_ for a few seconds and then
exit. Only then is mythtv happy - but it's very happy on both tuners! Weird.
