Not neccessarily. It could a bug in one of the drivers using IRQ 21 (sata_nv or the nvidia ethernet), it could be another inactive device, or it could be a hardware funny. Nvidia stuff can be quite hard to diagnose as we have no documentation but we can try. The first question is whether it is network or disk triggered - seeing if heavy loads to one or the other trigger the problem might be a first plan.
