I posted my first bug to bugzilla on redhat.com today. It seems the new kernel (2.4.18-17.8.0) has an issue with my Dell Inspiron 8100. My unofficial conclusion is "the maestro3 module causes esd to peak my CPU for an indefinite amount of time". I have to be able to listen to music while I work!!
I can't wait for the release of 0.4 (coming very soon)... I haven't compile the CVS version but I was told it's made a lot of progress since 0.3 and becoming quite usable.
