Glad to know I'm not the only one suffering from this issue.

I already did some tests, but could only collect some hints. I'm far
from having a clear vision of what is really happening.
Sorry for my lack of debug skills.

I'll upgrade microblaze to version 7 to see if this issue is resolved.
Thanks to Goran for the suggestion.
Then I'll rerun the various tests and let you know.

Thanks for your time.
Giulio Mazzoleni
