I have two Raspberry Pi 3 model B; one from element14 (made in PRC), and one from another vendor (made in UK). The other vendor's board works as expected, including WiFi. However, I cannot get WiFi working on the element14 board at all. It looks like the device isn't initialized correctly.
Here's the log from the non-working board, including manually removing and re-loading the brcmfmac driver:

Has anyone else had problems like this? Any ideas, or do I have a hardware problem?
