have good reasons, staying at older versions is recommended.
I would love to, but I couldn't get my software running with 2.3.
I had to convert (a month ago) my software from RTLinux to Xenomai
having only a few days for it. I have a kernel module and an app
that talks to it. I use the posix skin. But with 2.3 apparently
I had to load posixio and something (forgot) manually, but I just
couldn't get these loaded. Since time was running out I decided
to stay with 2.2.5 for the time being (unfortunately).
I do understand. But once your time constraints relaxed a bit, please
don't forget to post remaining issues here. Maybe they reveal some real
bug.
systems (MSI 945P, Intel P4 3Ghz). My kernel runs fine on several
other/older systems, but on the new systems there is something going
on every 8 seconds. See output of latency test below. What could
this be? Is this an SMI effect?
Is CONFIG_XENO_HW_SMI_WORKAROUND selected? What does the kernel
output
tell you about if it's working? Do you have an ICH7 chipset on your
board? Would be another reason to update Xenomai (2.3 takes care of
it,
2.2.x doesn't)... :)
If this all doesn't help, have a look at this tool:

In any case, please give a feedback on the outcome.
Thanks. I will.
My problems have been solved. First I did Ulich's fix to enable SMI
detect/workaround for ICH7 on 2.2.5. That worked fine. All devices
continue to work and no more SMI induced latencies.
Then I tried Xenomai 2.3.0 again to find out why I couldn't get that
going some time ago. Gilles reported that if I user shared memory then
I should enable shared memory for the posix api. My first thought was,
"duh of course I have enabled that, I'm not stupid". Guess what? I AM
stupid! Now everything works on all systems.
Thanks everybody.
