A few weeks ago you made the following response re a problem with the usb DigiTV tuner, as noted below.
I have just installed a recent distro using the 2.6.20 kernel, and the problem still persists. Can you give me any idea when these patched will be included in a release kernel?

Many thanks,

Phil Taylor.

  11.. Edit nxt6000.c
  12.. Go to ~line 467 and add this line:
  13.. if (fe->ops.tuner_ops.set_params) {
  14.. + if (fe->ops.i2c_gate_ctrl) fe->ops.i2c_gate_ctrl(fe, 1);
  15.. fe->ops.tuner_ops.set_params(fe, param);
  16.. if (fe->ops.i2c_gate_ctrl) fe->ops.i2c_gate_ctrl(fe, 0);
  17.. }
  18.. 
  19.. Thanks to Alex Woods for fixing this... This will be merged into the master repository soon.
  20.. ( i will also see to it that the -stable kernels get updated with this patch )
  21.. Good Luck,
  22.. Mike Krufky
