Libertas firmware

George Hunt
I downloaded James new kernel. And found that it did indeed bring up the graphics chip, and considerable functionality.(light-dm seems to take 90%cpu for 30 seconds, before xfce desktop comes up -- a symptom I have not fully explored)

But when I looked at the dmesg, there was mention of not being able to load the libeertas firmware sd8686-v8.  The rpm which is in the fc22 repo for libertas came down as:

[root@localhost ~]# dnf download libertas-sd8686-firmware.noarch
Last metadata expiration check performed 0:10:53 ago on Thu Jun  4 14:01:59 2015.
libertas-sd8686-firmware-20150410-49.gitec89525 9.4 kB/s |  14 kB     00:01    
[DRPM] libertas-sd8686-firmware-20150410-49.gitec89525b.fc22_20150521-52.git3161bfa4.fc22.noarch.drpm: done                    
Delta RPMs reduced 0.1 MB of updates to 0.0 MB (88.1% saved)

[root@localhost ~]# rpm -qlp libertas-sd8686-firmware-20150521-52.git3161bfa4.fc22.noarch.rpm 
/usr/lib/firmware/libertas
/usr/lib/firmware/libertas/sd8686_v9.bin
/usr/lib/firmware/libertas/sd8686_v9_helper.bin
/usr/share/doc/libertas-sd8686-firmware
/usr/share/doc/libertas-sd8686-firmware/LICENCE.Marvell
/usr/share/doc/libertas-sd8686-firmware/WHENCE
[root@localhost ~]# 

So I cloned the dev.laptop.org/git/linux.firmware repo, and put the the sd8686-v8.bin and ....helper.bin into the /lib/firmware/libertas/ folder.

The dmesg  error message went away, and the wifi adapter could list beacons.

When I went back to verify, by removing the sd8686.bin-v8, and reboot. I still got no error.

I do not know whether firmware is persistent across reboots.  I "egrep'ed" all of the kernel, and could not find where sd8686-v8.bin is hard coded. 

Is this a situation where a symlink would be appropriate? (as in /boot for vmlinuz and initramfs)

I'm sort of in over my head. There's so much I don't know.

tried removing sdio8686.bin from /lib/modules/libertas again. And this time it failed (as I expected it to). Too much focus, or too much wine!

Time for bed

Briefly, you're saying that Fedora 22 firmware bundle for the wireless
device is no longer compatible with the hardware.  Thanks for the research!
