Hi Alan, thanks for your reply.

that file is already installed and seems to be the same with the one in the repository 

$ curl -s https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/ath3k-1.fw | sha256sum
e51feca60698858fdf8150135360a26fb4742323eea73a4d42f15410f00e7683  -

$ cat $(rpm -ql ath3k-firmware)  | sha256sum 
e51feca60698858fdf8150135360a26fb4742323eea73a4d42f15410f00e7683  -

$ rpm -q ath3k-firmware
ath3k-firmware-1.0-1.el6.elrepo.noarch

dmesg is still showing the "file not found ar3k/AthrBT_0x11020000.dfu" output. 


I see that the ar3k firmware directory is packaged via linux-firmware.rpm 
in EL7. It is packaged independently from the kernel.src.rpm [1]. 

$ rpm -qpl http://ftp.redhat.com/pub/redhat/rhel/beta/7/x86_64/os/Packages/linux-firmware-20131106-0.1.git7d0c7a8.el7.noarch.rpm |grep ar3k
...
/lib/firmware/ar3k/AthrBT_0x01020200.dfu
/lib/firmware/ar3k/AthrBT_0x01020201.dfu
/lib/firmware/ar3k/AthrBT_0x11020000.dfu
/lib/firmware/ar3k/AthrBT_0x31010000.dfu
...

for EL6 this package will conflict with the kernel-firmware.rpm and more.


For testing i did it manually 

mkdir -p /lib/firmware/ar3k/ && mv ~/AthrBT_0x11020000.dfu /lib/firmware/ar3k/
mkdir -p /lib/firmware/ar3k/ && mv ~/ramps_0x11020000_40.dfu /lib/firmware/ar3k/

in el7.noarch.rpm and the repository both files are still the same.

after rebooting the system these files get successfully loaded.

$ modinfo ath3k |grep -i e04e

this firmware files are needed

$ find /lib/firmware/ar3k/ -type f
/lib/firmware/ar3k/AthrBT_0x11020000.dfu
/lib/firmware/ar3k/ramps_0x11020000_40.dfu


so far ...
