Yet another test kernel for the FC2 daredevils! :-) 
I would dare say that this one works better than 2.4.x! (woohoo!)

To install (after you have planetedge in your repository list):
  apt-get install kernel#
To install the matching alsa driver:
  apt-get install kernel-module-alsa-

I have also included SMP builds (only i686 for now) but be WARNED, I
have not managed to boot into them on two uniprocessor machines. In both
cases the SMP kernel had problems that I think are related to interrupt
handling. I don't have a _real_ SMP system I can use, probably I'll try
on one tomorrow. 

For tunables and more details see last weeks' post:

This kernel also includes a patch for the radeon/mga/r128 dri modules.
Seems to be working fine so far. 

Anyway, in the FC2 planetedge repository there are also new versions of
alsa-driver, alsa-lib, alsa-utils and others, now up to a very recent
post 1.0.6a cvs snapshot. 

Let me know of any problems (or successes).
