I would think so too, but the card was actually in a hung state with  
the original values I was reporting.  I couldn't actually lock onto a  
signal (I just didn't realise at the time as tzap was reporting a  
channel lock).

What is really strange is that I attempted kernel 2.6.22-2 (debian  
sid), firmware v 1.10 and the latest HG drivers, but then I lost one  
channel.  So I rolled back to 2.6.22-1, firmware v 3-beta1 and HG  
drivers from 2007-8-26.  Now I did get back to the original  
performance.  Until i cold booted to fix this hang, and now I've lost  
my channel again (the same as after the upgrade).

These are some really strange bugs... and I'm having trouble  
narrowing it down.

Can anyone please help with the process I should take to find where  
the problem is originating from?  What is the best way to eliminate  
possible problems?

Dan
