Out of curiosity I went ahead and tried that, but I think it is not really necessary as
more recent kernels theoretically already have that firmware.
In any event, it did the same thing.
I have
downloaded the firmware tarball, and perusing the contents after extraction there are atheros drivers; but, they all seem to have to do with the wireless, whereas I am not using wireless.
It may or may not have to do with my using a gtx980 card. It's relatively new stuff for Debian to handle, and the issue seems to be that it kicks me to a blue screen that begins to take keyboard input as if it were a command line...!?!!?!?!? But with no command line functionality. Alt-f2 gets me to that limited command line as one might expect, but I don't really know where to go from there.
Really confusing.
