[linux-dvb] i2c ack_error

I have an Air2PC ATSC PCI card running a Fedora Core 3.  Using the CVS 
drivers with kernel 2.6.11-5 segfaulted on the modprobe (i can post a 
trace if anyones interested), but on 2.6.10 it loaded ok aside from this 
i2c ack_error.  dvbscan -cvvv works in a sense that it finds 4 programs 
from the PAT/PMT, and azap shows a signal lock, but cat 
/dev/dvb/adapter0/dvr0 > blah.ts does not produce any output.  We also 
have a data pid on 0x2a here and I can not get data up from the dvb0_0 
interface.

If anyone could point me in the right direction it would be great.

Thanks,
Sean
