According to this:
This partial wakelock will occur when your phone seeks reception for example.
I personally have no idea if you can stopp this process and I highly doubt, that stopping this is a good thing (at least if you want to make calls with your phone).
Yeah, I was wondering about the RILJ one too. Does it get worse when you don't have good reception? Or is it always there?
I read somewhere that it can be reduced by turning off location services. You might want to try that.
