Yes, something like rpm -i --nodeps <package>.rpm but the .deb version.

No, but I'm using it for Software defined Radio ,SDR, application feeding quadrature inputs to the sound card, hence the importance of having all the sampling rates available > Are you running rtirq etc? > No I'm not using that. > <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.
