i2c fails to read the subsystem from the eeprom.

Confirmed here again for the complete eeprom content.

Nothing about the IR, but at least all tuner modules seem to be
correctly loaded.

What was your last good working kernel and was your eeprom already
failing there too, or is that new?

Usually such is caused by bad contacts of the PCI slot or by a bad PSU,
but we have reports from a Pinnacle 50i with the same i2c remote.

It has i2c troubles (ARB_LOST) and then also problems on loading the
tuner modules correctly. With disable_ir=1 for saa7134 it became at
least somewhat usable again.

But for the 310i is another problem reported starting with kernel
2.6.26.

The 310i and the HVR1110 are the only cards with LowNoiseAmplifier
config = 1. Before 2.6.26 two buffers were sent to the tuner at 0x61,
doing some undocumented LNA configuration, since 2.6.26 they go to the
analog IF demodulator tda8290 at 0x4b.

This was bisected here on the list and is wrong for the 300i.
Thread is "2.6.26 regression ..."

The HVR1110 using the same new configuration seems to come in variants
with and without LNA and nobody knows, how to make a difference for
those cards. At least still no reports about troubles with the new LNA
configuration there.

The attached patch against recent mercurial master v4l-dvb at
linuxtv.org tries to restore the pre 2.6.26 behaviour for DVB-T on the
300i.

It changes also the i2c remote address of the Upmost Purple TV from 0x7a
to 0x3d, since recent i2c on >= 2.6.30 complains about it as invalid
7-bit address, just in case.

Good luck,

Hermann
