Here is the second release candidate for the v2.2 branch. Short log

Sorry for reporting so late.

But as my tests did not yet include starting up my board I did not notice
that changes (probably between 2006-05-10 19:30 and 2006-05-11 20:31) made
my board unbootable.
The board hangs after emitting "(Engines Of Creation) loaded." output is:

TIMER IRQ is 32
I-pipe: Domain Xenomai registered.
Xenomai: hal/powerpc started.
Xenomai: real-time nucleus v2.2-rc1 (Engines Of Creation) loaded.

I have no ideas why, as my PowerBook is running fine with an actual Xenomai
based kernel. But I now that the timer architecture for the PPC40x family
is quite different to the PPC en general.

Any ideas where to begin debugging? I am familiar whith the timer/interrupt
architecture of the PPC405 but a hint would be welcome. I will take my BDI
debugger from Abatron home to have a look where the processor hangs, but
will not have time till tomorrow or Wednesday to dig into this problem.

Could you try building all skins as modules with only the nucleus
statically built into the kernel? I'd like to know whether the lockup
occurs when one of the skin attempts to initialize, or if the problem is
in the early Xenomai bootstrap. TIA,
