Agree... in that notebook there is a problem with DMA..... the
nautilus-cd-burner complains about it...

Thanks very much for your infomation... I will fix my installation with
that patch in
the /usr/src/sys directory...
I tried to change the buffersize to 4096 or less but still does not
worked the modules
fails to run in my 6.1-RELEASE because of a call to mix_setparentchild
that does not exists
in the sound.ko module in the 6.1 RELEASE... so I had to comment the
code too...
Anyway was for me a good "exercise" watching how the module is coded
( I have much to learn
from the masters, like you....)
