The problem summary is that running ieee1394 ISO traffic can cause

Do your patches to lower CPU utilization show any influence?
Not tested yet. I have a hunch that the removal of the dummy read might
improve the situation. But I haven't investigated this yet.
Do you get 1394 bus resets while ieee1394stress is running? (You could
e.g. print raw1394_get_generation(handle) when it starts and when it exits.)
As far as I can tell there are no bus resets, but I'll check.
