C and experience this behaviour: when I try to install packages from commandline, the installation manager starts quick and reads the package(s), but after that it stays dead quiet like it's frozen. ps -ef shows it's just going on, no defunc or anything like that. Also, when I want to watch the processes using top, it starts, but nothing shows. When I want to end it, Ctl-C gives no response giving me no other option than to use kill. Is this a known behaviour when running Xenomai ?

FWIW, I only test xenomai with tftp + nfs, even the U-boot script is not
on the board itself. Xenomai 2.6.3 with linux 3.10.18 has been tested on
the pandaboard, which has exactly the same ethernet chip as beagle-xm
(from what I see in Huub's dmesg). The only difficulty for me was the
missing USB transceiver in the kernel configuration.

Generally, before you report a non-working configuration of Xenomai,
with a certain version of the kernel, please try the exact same kernel
configuration without Xenomai.
