So the two Technotrend ones work well for some time and then develop the
issue? Have you always swapped out the same Technotrend for the KNC1 or have
you also tried swapping out the other Technotrend (just to rule out that one
of the Technotrend adapters is flakey). One thing worth trying (which you
may already have) is to try different PCI slots to rule out shared interrupt
issues. It seems both the KNC1 and the Technotrend adapters are based on the
same chipset, but who know s it may make a difference.
