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).
[ 0.000000] Linux version 3.2.0-rc4-rt5 (root@babelfish) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #1 SMP PREEMPT RT Tue Dec 6 01:22:11 NZDT 2011 [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.2.0-rc4-rt5 root=UUID=ca21e0bf-b7f8-45c3-8fc9-066c4dd6052e ro quiet splash
What next? Should I try moving the Ethernet card to other slots and see if anything changes?
