Hi Michael,

I can not reproduce this issue on another armv5 I have, but it does not
support iwmmxt. So, in order to see if the problem you have comes from
iwmmxt, you should try and build a root filesystem with a soft-float
toolchain, such as, for instance, the codesourcery toolchain.

Currently, iwmmxt floats are not supported with Xenomai, so, if you want
to get them working, something will have to be done.

Regards.
