The only system that I have that can run the RTL8188CE is 2 GHz. >> connecting to more than one AP?

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. Larry
