Yes... And it is not the problem, as I make use of interrupt
sharing on the first three slots.

Yes, one could think. But I checked that interrupt handling basically
works for slots 4+5 with "cat /proc/interrupts". As soon as
I start a larger ftp data transfer over an ethernet adapter in
one of these slots the problem occurs.
