i could never refuse a whopper with cheese ... so bad for me, but  it's
all about the anticipation :)

well, i'm keepin the configuration i've got with my (self!) compiled
alsa, but there's no way i can resist at least checking out a new CCRMA
kernel ...

and, while everything seems to *run* ok for the five minutes i used the
edge update, i get this in dmesg:

point taken :D

in any case, had band practice tonight and took my CCRMA box along
(configured as mentioned in my previous post) to provide drums and
multi-track recording - performed admirably for 3 hours straight ...
that's what i like :)
