It seems that hardware is faulty, although in a very "interesting" way.
We tried changing the "slot" modules with 4 NICs each, which did not
change matters. However, another similar hardware appliance works. I am
thus not sure which component is at fault here, as (parts of) the NICs
were changed. Maybe the interrupt controller is weird on the "faulty"
box? ACPI issues? If anybody wants to track this any further, I am still
willing to test patches.

best regards,
Rene
