Hi everyone,

Is this a well-known problem also in other ports ? or have anyone of you a
suggestion to solve this ?
If you are using the default openpic initsenses in prep_pci.c then you
might see this problem since MPIC input 1 now has the 550 UART. You'll
need to change the initsenses since the edge triggered ECC interrupt
used to be on input 1 on the older boards.

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.
