Get the box to be : as idle as possible, and then use vmstat -i or stat -vmstat to see if : anything is spewing interrupts. Also, make sure that you aren't sharing interrupts between GIANT-LOCKED and non-giant-locked cards. This might be exposing bugs in the network layer that debug.mpsafenet=0 might correct. Just noticed that our setup here has that setup, so I'll be looking into that area of things. Warner
