[fedora-arm] Rawhide 22 wandboard quad kernel warning
I have a wandboard quad that is running Fedora Rawhide 22,
updated yesterday to the latest packages.
I am using wired ethernet, and Fedora is installed and running
from a SATA disk, but using a micro SD to run uboot and load the
kernel. Everything else is on the SATA disk.
I get the following warning, typically only once per boot-cycle.
The kernel otherwise appears to run properly.
Should I file this in bugzilla? I'm a bit new to how Fedora ARM
devs prefer to receive reports like this. (I.e. discuss here
first, or go right to a bug report?)
