I have an application running on a 7350. This includes the gpsd daemon. 
Everything is going pretty well except that there are regular CPU spikes every 
10 seconds or so. I ran 'top' in another ssh session and it looks like the 
process causing the spike is the tsscarda (SD disk). Does anyone know if this 
is normal or what I might be doing to cause the issue? Could it just be from 
reading/writing to the disk? I turned off the process that writes a small file 
to disk but still have the issue. I also lowered the priority of gpsd to 0 
(renice).

Any ideas/thoughts are appreciated.

Thanks,
Steve
