Looking forward 6 months to a year from now, I realize it will make my
life much easier as I begin to deploy and maintain at least 30 and
possibly as many as 100+ linux based broadcast workstations.
Again, sorry for saying that. Lost my head there.
Lee, your efforts are very much appreciated, too.

I don't know about Free but I'd rather not be building kernels forever,
it'd be nice that in a not too distant future regular unadulterated
linux kernels would be good for audio/midi work... On Wed, 2005-07-13 at 13:52 -0400, Lee Revell

I'm confused ... most of us build our own kernels

It is a config option, the available settings are 100, 250, and 1000.
The problem is that the default has changed to 250.
Update: Linus has said that
this is a done deal. So now we need to
figure out how to work around it. I guess we'll have to go back to
using the RTC like on 2.4.
