Please keep replying to all (including Cc:).

Did you disable runtime-pm for the mmc host controller with bcm43241 
device. From your log I see the driver tells the firmware to join 
"BRAINNET 1" but wpa_supplicant times out after 10 seconds. I suspect 
the host controller went in runtime suspend so the connect events from 
the firmware are not processed until wpa_supplicant gives up and host 
initiates interaction with the device.

The controller should be somewhere under 
/sys/bus/acpi/drivers/sdhci-acpi/. If you have the correct controller 
there is a power subfolder. Check the control file:

$ cat control

If it says auto, change it to 'on':

echo 'on' > control

When done, load brcmfmac.

Arend
