That's pretty much the first thing I do on a ubuntu box, but more to get mail and other network-related stuff working. What do /var/log/kern.log, and perhaps /var/log/messages say? Being persistent across boots, I guess they're your best bet for diagnosis. If the wheels are falling off in rtai, then hopefully it'll squeal there. As for regular disk activity, they all seem to do it these days, whether ubuntu or debian - mine is doing it every 7 seconds or so. > Also, gnome-power-manager is in the top 20 of the htop list. > > Perhaps that might be disabled also? I've just killed that process on a non-rt ubuntu 8.04 box. After twenty minutes, it hasn't been auto restarted, and I haven't noticed any issues. (Had to boot another host, since this debian 7.8.0 box has no gnome-power-manager to begin with.) Not sure if this is the latest version, but have you run an eye over the things to check here?: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting#Checking_the_RealTime_subsystem That "pcspkr" is sufficiently vague to make one wonder. This is admittedly fox hunting in the dark without a spotlight, but if I've set something running, mebbe someone else will plug it.
