I am starting to agree with all you say here !

but (sorry, there's always something) there was one tiny flaw in my 
conclusion that it wasn't hardware. One difference I did not take into 
account is that the ringbuffer was being to written to the ide drive, 
not the SATA.  I have found that I can provoke the glitches even in 
Knoppmyth, by writing the ringbuffer to a temp directory on one of the 
SATA drives instead of the IDE.

I now officially dislike SATA drives.  This was my first machine using 
them, and had all sorts of initial problems.  Now this.  Time to get a 
nice big reliable IDE drive I think.
