Changed motherboard, Same NICs, Interrupt CPU went up

Derelict

I just changed from a Jetway D510 to a Jetway JBC200F96 D525. I moved the same 3xIntel GigE daughtercard from the old machine to the new. My interrupt CPU has gone from effectively zero to about 20%. Both 2.1.4. Backed up and restored the config to the new machine.

Any thoughts?

Got into the BIOS and disabled the parallel port. All better.

Your parallel port, ppc0, is doing something. I doubt you're using it so try just disabling it in the BIOS.
