I was looking for some dma errors from the cx23885 driver, these usually occured while streaming is being attempted. Attached to this email is another patch. The difference between the first one and the second one is that I load an extra module (cx25840), which normally is not required for DVB as it is part of the analog side of this card. This does NOT mean analog will be supported. As of today the main v4l-dvb can be used with this patch and this means that the cx23885-leadtek tree will soon disappear. So step 2 above has been modified to: "Check out the latest v4l-dvb source". Other then that step 4 has a different file name for the patch. Steps that need to be completed are: 2, 3, 4, 5, 7, 9, 10 & 11. (As you have completed the missing steps already). If the patch works, please do not stop communicating, as I have to perform one more patch to prove that cx25840 is required and my assumptions are correct. Once this is completed I will send it to Steven Toth for inclusion in his test tree. This will need to be tested by you again, and if all is working well after a week or more it will be included into the main tree.
