The problem summary is that running ieee1394 ISO
traffic can cause
scheduling latency spikes up to 1ms, even for RT threads with higher
priority.
Do your patches to lower CPU utilization show any influence?
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.
