Thanks for that Florian. I'd checked on Fedora 7's version of util-linux, and the old schedutils tools are there. The version on Lenny is 2.12r-19. I'll go for the later Sid version, and hope it installs ok. I'm still trying to find out why Marcos's rtirq from the musix repo is not being started. It appears to have something to do with, when it installs, it creates a sysconfig directory in /etc, and puts rtirq in that, rather than in /etc/default, which is where it should be. If Sid's util-linux installs on Lenny ok, I think I'll install rtirq, which will create an /etc/sysconfig directory, then make a symlink from /etc/default/rtirq pointing to /etc/sysconfig/rtirq, and see if that resolves the problem with rtirq I had on Etch, before I used chrt to change the priority of the soundcard to 90, which fixed the realtime problem on Etch. I know rtirq isn't running on Etch because sysv-rc-conf shows runlevels 2,3,4,and 5 unchecked, and trying to run /etc/init.d/rtirq status, just segfaults, as does /etc/init.d/rtirq start. I'll post back either way, as this may be usefull to someone wanting to get realtime working on Debian. Thanks for your help.
