I heard from the Realtek engineer already, and he reminded me that we know of 
this problem. One pin of the PCI interface is not correctly powered, and that 
causes a boot from efuse to fail. The troy branch has code to work around this 
condition; however it was not turned on. If you pull again, this option is now 
enabled. See https://github.com/lwfinger/rtlwifi_new/issues/3 to read what has 
previously been posted.
