I've started working on MCPN765 port, since I think MVME5100 is an MCPN765
with a VME Bridge and without an ISA bridge, so I think the senses of
interrupt are correct because the 5100 and the 765 manual page related to
the interrupt senses is exactly the same (or it is a cut&paste error ??? :))
However this problem, like many other I've encountered, are all due to a bad
cross-compiler :(. I start working today with a good environment after a
month of nightmares !

Thank you very much for the help.
Stefano.
