Description Philippe Valembois 2012-11-11 13:03:12 UTC 
The WinTV HVR900 DVB-T usb stick has stopped working in Linux 3.6.6.
The tuner fails at tuning and no DVB channel can be watched.

Reverting the commit 3de9e9624b36263618470c6e134f22eabf8f2551 fixes the problem and the tuner can tune again. It still seems there is some delay between the moment when the USB stick is plugged and when it can tune : running dvbscan too fast makes the first channels tuning fail but after several seconds it tunes perfectly.

Don't hesitate to ask me for additional debug.

Can you post this summary to linux-media@vger.kernel.org that should reach the relevant people.

also if the breakage is within stable (ie 3.6.x x < 6 worked) then cc greg@kroah.com the 3.6 stable maintainer to get the patched backed out of 3.6.x

I can't reproduce the bug anymore.
