I've tried with the v478 firmware (was using 410.2160 earlier).  I do 
not see the 'Fatal DMA error' messages anymore.

On another note, however, I can't connect to a network.  The device 
seems to alternate between being idle, and scanning for APs.

I've attached the relevant portion of my dmesg output for your review.

Where would I got about finding the v5xx firmware?
