[PlanetCCRMA] Re: atl1 driver; sleeping function

Hello,

At the end of July 2007 I posted a message saying there were problems
with the atl1 driver in the rt kernel.  A patch was provided that
fixed the problem, but it does not seem to have been applied to more
recent versions.  Would it be possible to do so, or will I need to
apply the patch each time a new kernel comes out (e.g., if the driver
with the patch is unstable)?  Stock Fedora kernel is fine.

Relevant info:
