So there is something unhappy in your system about the way how the threaded irq handling works. Can you please provide the output of lspci -vvv and a full boot log (any 3.0/3.2 kernel you have handy)?Attached. :)Could you disable the e1000 for a test? Just boot up and bring the interface down. Does that change the situation?
Yes - I tested with 3.2.0-rc4-rt5 (and it actually is an RT kernel this time - see below!) and with the Ethernet interface down, it seems to be working properly. Even Pure Data didn't cause any crackling or stuttering (other than when starting up).

What next? Should I try moving the Ethernet card to other slots and see if anything changes?
