that they are "fine" - merely that it doesn't trip over the problem. It's<br>
kind of like being told your car's brakes are possibly defective and you<br>
should avoid heavy braking - and your response is to choose a path home that<br>
doesn't involve any heavy braking and then saying your brakes are "fine".<br>
<br>
It's even more worrisome that people are suggesting "just turn it off"<br>
without being able to point at a reason *why* it needs to be turned off.<br>

Which gives you more confidence:<br></blockquote><div><br>Totally understand your points. However, Xenomai has been in many distribution, like Ubuntu. it is simply a kind of interest to get something to work. I had been an embedded engineer for many years, ( but never dealt with Linux or Linux kernel). There are many Realtime OSes out there, but costs a bomb and for hobbyist like me would not spend money buying it. Having said that, there are a few open realtime patches that make LInux to be realtime, deterministic. To what level, I am going to test it out. That is my intention. If you are interested, please have a look at <a href="http://www.xenomia.org">www.xenomia.org</a>. <br><br></div><div>It has nothing to do with confidence, it is pure experiment, hobby.

NVidia's modules won't work on a kernel defined with LOCKDEP enables, we<br>
don't know why, so just turn it off..<br>
<br>
versus<br>
<br>
NVidia's modules won't work on a LOCKDEP kernel because with that defined,<br>
the locking functions called by the module are redirected to debugging LOCKDEP<br>
variants that are EXPORT_SYMBOL_GPL. When you try to modprobe it, the _GPL<br>
variants aren't available to the NVidia module due to its licensing, so you<br>
get 'unresolved symbol' errors. This information should be enough for you to<br>
figure out how to fix your personal copy and make it work (but not to make<br>
that copy redistributable).<br></blockquote><div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

See the difference?<br></blockquote><div> </div></div>The kernel I work is for Pandaboard. Hence NVidia will not in the picture. </div></div></div></div></div>
