Subject: [linux-dvb] Problem in 2.6.28 kernel with dvb-usb
Date: Sat, 3 Jan 2009 20:09:49 +0200	[thread overview]
Message-ID: <6B1623AD-5F0B-479B-9574-44B87530ECF2@gmail.com> (raw)

Hi,

I compiled 2.6.28 kernel to my Fedora 9 setup yesterday and my Artec  
T14BR DVB-T USB stick stopped to work properly. It is recognized  
correctly but when the stream receiver is started I get this message:

kernel: dvb-usb: could not submit URB no. 0 - get them all back

and no sound or picture is played with vdr. This happen 9 times out of  
10. And that 1/10 time the reception is very bad. My previous kernel  
compilation is 2.6.28-rc6 and the device works just fine with that  
kernel.

Here is the snippets from dmesg and /var/log/messages:

2.6.28 kernel:
