Could you format your mails correctly to make them readable? Use text,
not HTML, truncate at 72 characters, and use > as a quotation mark,
meaning that one '>' is the sign that you quote someone, two '>' is you
quoting someone who quoted someone else, etc... I am really sorry to
have to tell you about this, this is really basic knowledge of the
netiquette, we should not have to tell you about it.

The result of rt_timer_read is a long long, so, if you cast it to an
unsigned, you loose the most significant bits. So, the result is totally
meaningless. This again, is basic knowledge of the C language, we should
not have to explain.
Your bug report is quite insufficient, we do not even know what version
of Xenomai you use, maybe you are reporting a bug which has been solved
a long time ago. Neither do we know what version of Linux and of the
Adoes patch you use, or the contents of your .config file. We do not
have a self-contained example that we can run to try and reproduce your
issue.
So if you want some answers, please give us the means to answer you.
