issues with af9015

Hi,

I have same issue with two different af9015 cards made by 2 different manufacturers with 2 different frontends.

When card is used with tvheadend software which constantly does idle scanning, after 1-2 days it starts showing following dmesgs:

[342924.332308] tda18218: i2c wr failed ret:-1 reg:1a len:3
[342925.152277] af9015: command failed:1
[342925.152293] tda18218: i2c wr failed ret:-1 reg:1a len:3
[342925.973596] af9015: command failed:1
[342925.973610] tda18218: i2c wr failed ret:-1 reg:1a len:3

Only way to recover it from this state is unplugging. Rebooting doesn't help as card stays powered during reboot.

Any idea what can cause this? Can I do any further debugging steps?

Thanks,

damjan
