DiB0070 I2C read failed errors on Sony playTV dual tuner.

Hi Guys,

As far as I can tell Googl'ing around this error has been aroung since 2008 in the dvb-usb-dib0700 driver.

I get the following in the log:

[  271.882232] DiB0070 I2C write failed
[  612.809450] DiB0070 I2C read failed

[ 2011.890312] DiB0070 I2C write failed 

When there is enough of them in the log, the tuner stops working. It has crashed at the point as well, see:

Anyone know how I can fix this? I have tried upgrading to the latest kernel 2.13 and have compiled and installed the latest v4l drivers.
I have also tried vairous module parameters for the relevent modules. i.e

options dvb_usb disable_rc_polling=1
options dvb_usb_dib0700 force_lna_activation=1
options dvb_core dvb_powerdown_on_sleep=0

Nada!

Any help much appreciated.
