Hello,
I get the following message and a completely frozen system when I run my
applications after upgrading to branches/v2.3.x rev. 2137. (Everything
worked fine on revision 2077)
'Xenomai: fatal: re-enqueuing a relaxed thread in the RPI queue'
Maybe I did s.th. stupid again?
I did 'svn -r 2137 up' in the source directory and recompiled
everything (kernel, xenomai, my application). It's a AMD-X2 with Kernel
2.6.17.14, running Debian Sarge. My colleague tells me he saw the same
when experimenting with trunk.
some additional infos:
'svn info' gives me:

No, I did, by committing a half-baked patch attempting to fix a priority
inversion seen with the pSOS emulator. Now really, really fixed by #2139
in v2.3.x, and #2140 in trunk/. Hopefully.
