This should only affect devices that use nxt200x module, but perhaps there is something going on that is causing interference on the i2c bus of your card? This is just a guess.... Results from your cvs test will show us some better information. If you are successfully loading cx88-dvb WITHOUT nxt200x module (before the cold boot) then the above is not the case. Meanwhile, I repeat, it is well-known that the media tree is broken in 2.6.15 ... I think we'll get better results after Hugh Dickin's sends in another patch. In the meantime, you can test the v4l + dvb code using the merge-trees build method on the cvs repositories.
