What is your system architecture? $ uname -r will probably tell me what you need. Is this a dedicated audio production machine? Are you running rtirq etc? http://www.rncbc.org/drupal/node/333 (thanks RM). <snipped> > So how do I just down load a kernel with the minimum deps to allow > it to function, so I can test and see if the problem occurs with the > alsa packages in their current working state. > > TIA # apt-get --no-install-recommends linux-image-3.0.0-1-whatever_your_architecture I'd suggest you run this first:- # apt-get -s --no-install-recommends linux-image-3.0.0-1-whatever_your_architecture > /root/kernel-3.0.0.0-1_upgrade That will give you a list of changes for future reference. Ralf Mardorf will surely have an opinion but he won't be back online until later this today (at earliest).
