Hello,

I've been plagued by overruns, I know it's probably linux device
driver issues, but wanted to see if anyone could possibly help me find
the heart of the issue:

I have ecasound output (at bottom) to show that it's getting
interrupted for up to 6 seconds, and all I really need to know is how
I figure out what the problem device driver is, so I can file a more
specific bug.

Computer: A7N8X Mobo with Athlon 2700+
