Same symptom with a slightly different set of steps leading to the problem. - boot / telinit 5 OK - su'd to get privileges - cat /proc/sys/kernel/preempt_wakeup_latency (showed 0) - echo 1 > /proc/sys/kernel/preempt_wakeup_latency - set RT priorities as before - started scripts to record data - system-config-soundcard (newline shown) At this point, the system is locked up again with no response to any inputs.
One thing I did notice from the previous test, I had two output files from preempt_trace showing a couple minor (just over 50 usec each) wakeup traces.
I have a few ideas to simplify the set up to see if I can get some useful data out of the system.
