Sorry for not being clear, and I agree with you -- something is ***seriously*** broken with a capital B. What I have just done (and in the middle of things) is going back to a clean config (generated by my distro's live boot), and using that as a starting point for a complete overhaul. My development machine (an Acer 5720z laptop with an Intel T2330 core2duo processor, etc.) had serious config problems when I first bought it a few years ago. I had to tweak a bunch of things in the kernel to get most of the stuff to work at all (since a number of things were not fully supported yet). My latest config (for a 2.6.27-r8) seems to be borken with a capital B, so I'm going through and testing various tweaks to the base config. > What kernel are you using? I was getting this same behaviour on both 2.6.24 and 2.6.27. I'll report back what I find once I get things configured back up... Sorry again for the confusion of the RTAI latency tests vs. HAL's. BTW, this point should likely be clarified in the build documentation. The instructions I was reading were not entirely clear to me.
