Re: [gentoo-amd64] AMD64 - 2.6.14-rc2-rt7 - great for real time audio

[Tres Melton]

Mark,

	You have had so many problems with the other kernels doing this stuff
and now that you have found a good one I really think that you should
compose a message entitled "Latencies in the kernel" and post a summary
of your experiences with the various kernels to the LKML.  I think that
it would benefit the developers (and all of us) to know that the kernel
seems to be tuned rather nicely now to tasking these things.  Anyway,
I'm glad that it is working for you.

Regards,
Tres
