[mythtv-users] Sudden Comcast Motorola 6200 Firewire Problems

[Todd Greene]

Hi All,

After months of near-perfect firewire connectivity with a Comcast 
Motorola 6200 box, the firewire connectivity has suddenly, completely 
failed.  I haven't upgraded *anything* (I'm using Myth 0.18).  I'm 
suspicious that this might be related to a Comcast upgrade of the 
firmware in the Motorola 6200 (or, my motherboard and built-in firewire 
connectivity is failing).  Now, when I plug in the firewire cable to the 
myth box, I see the following in /var/log/messages:

 kernel: ieee1394: SelfIDs failed root check
 kernel: ieee1394: Error in SelfID stage, resetting
 kernel: ieee1394: Error parsing configrom for node 0-00:1023

And so on...
In fact, I've been recently experiencing system hangs on the same box, 
which is likely either the result or cause of the firewire problem.  
Google searches haven't turned up anything.

Any suggestions?

Thanks,
