I cc'd Michael since he made several recent tda18271 changes.

This page: http://cvs.linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner
suggests that the card might work, despite the error messages.  Does
yours work?

I see that tda18271_write_regs() uses i2c_transfer(), which uses the
adap->algo->master_xfer function pointer, but I don't know enough to
figure out which master_xfer implementation might be used on your
system.  A complete dmesg log and lspci output might have a hint.

Can you reproduce this on an upstream kernel?  It would be good to
make sure that it's not something introduced by an Ubuntu patch or
fixed since the Ubuntu kernel snapshot.
