I think that all are in wireless-testing.

My search shows that the clock rate for this processor is 1.4 GHz. The only 
system that I have that can run the RTL8188CE is 2 GHz.

I thought the locking in the Power Save routines was OK, but perhaps there is 
some raciness that is exposed by the difference in speeds. The lack of 
diagnostics on the netconsole is a problem.

Do you have kernel debugging turned on for the lock diagnostics, and the Detect 
Hung Task configuration variable? Perhaps we can get some logging that way.

Have you tried the vendor's driver from www.realtek.com? I don't think it will 
make a difference, but it could be worth a try.
