Details

I am using Arch on an HP Slate 2. The 3.0 kernel on the current live image works directly, wlan0 shows up in network configuration tools and works, using the ath6kl module. (in fact, the 3.0 kernel only works in the failsafe mode, but that is an another problem)

However, after I did a system upgrade just now and rebooted, wireless stopped working. The reason, I see, is:
"ath6kl: Failed to get board file ath6kl/AR6003/hw2.1.1/bdata.bin (-2), trying to find default board file."

To fix this, in /lib/firmware/ath6k/AR6003/hw2.1.1/, I copied bdata.SD31.bin to bdata.bin, reloaded ath6kl, and it started to work. I needed to choose randomly between the three bdata.*.bin files.

I assume this is a bug in either core/linux-firmware 20120227-1 or core/linux 3.2.8-1.

I currently have no ability to easily copy and paste more stuff, so this shall suffice as of now.
This task depends upon

I do get very unstable behaviour using the beforementioned fix and need to keep reloading the module and reconfiguring the network under heavy usage. I am guessing it isn't exactly related to the original problem though.

Can you report this to the kernel developers?

Yes, this needs to be fixed in the kernel. The driver needs to know which bdata.bin file it wants.

Still a problem with latest packages? Did you report this to the kernel devs?

I had access to the device only at that time, and I didn't do anything else than report the problem here.

It does look like the problem might exist on new kernels too:
