Can someone please help me find a link to the open letter to kernel
developers regarding horrible latency with kernel 2.6 that Paul Davis,
Benno Sennoner and others posted to LKML in early 2004 (NOT the one from
2000) - the one that led Ingo to develop the voluntary preemption
patches.
I cannot find it with any amount of googling, and my local LKML archive
only starts in July 2004.
There was such a letter right? Am I crazy or just making this up?

Hi;
Are these the threads you are refering to?
2.6.X, NPTL, SCHED_FIFO and JACK :
http://lkml.org/lkml/2004/6/30/104
(In my archive; which consists only of posts I have read on lkml,
this is the first for Paul Davis in 2004, after that it mostly
seems to be responses to Ingos patchs.)
[announce] [patch] Voluntary Kernel Preemption Patch :

I was looking for the thread(s) referenced in the above message:
"Because of the recognition by kernel developers that 2.6 does not
perform as well as 2.4+lowlat (the Andrew Morton patches) when it
comes to scheduling latency, most audio developers and users have
remained with 2.4. Recently however, several brave souls have
attempted to test 2.6. The results have been mixed."
