I have an EPIA M10000N system with the same IO chipset and have seen  
that DMA thread before when investigating why my system was  
periodically locking up. In my case it actually turned out to be the  
2.6.9 kernel's support of Longhaul CPU speed control - upgrading to  
2.6.10, which has this turned off by default, has left me with a system  
that runs for weeks without fault.

I didn't find any reliable way to trigger the lockups though, so if it  
freezes every time you try live tv, then this is likely another  
problem.
