[elrepo] kmod-ath10k firmware issues (?) with CentOS 7

[Sean Hancock]

I successfully installed the firmware package: sudo rpm -Uvh ath10k-firmware-2.0-1.el7.elrepo.noarch.rpm

But, no joy:

[ 0.000000] tsc: Fast TSC calibration failed
[ 2.736679] snd_hda_intel 0000:00:1f.3 failed to add i915 component master (
-.9)

Exception AttributeError:"'NoneType' object has no attribute 'udev_unref'"in<
bound method Context.__del__of ,pyudev.core.Context object at 0x2947890>>ignor
ed


The only difference between now and before is that the following lines have gone away:

[ 4.254938] sd 4:0:0:0: [sdc] No caching mode page found
[ 4.255009] sd 4:0:0:0: [sdc] Assuming drive cache: write through


I also ensured I had the recent version of kmod-ath10k: kmod-ath10k-0.0-4.el7.elrepo.X86_64.rpm.

Any suggestions on how to proceed?

Sean

 There is an
 ath10k-firmware package e.g 
 http://elrepo.reloumirrors.net/elrepo/el7/x86_64/RPMS/ath10k-firmware-2.0-1.el7.elrepo.noarch.rpm
