Description of problem: After installing Fedora 25 XFCE Spin (beta), I am getting the message "Failed to find cpu0 device node" during the boot process. It does not seem to do any harm though and boot continues normally after that message. I found a similar bug that happened on Fedora 22 [Bug 1274821 - failed to find cpu0 device node error with kernel 4.2] Version-Release number of selected component (if applicable): $ uname -a Linux mousefx 4.8.4-301.fc25.i686+PAE #1 SMP Tue Oct 25 00:24:54 UTC 2016 i686 i686 i386 GNU/Linux How reproducible: After installing Fedora 25 XFCE, and booting to the system, the message will always be displayed (on boot, before Fedora loading screen). Additional info: System/Laptop Acer Aspire 5733Z 4GB RAM

Josh Boyer has explained that this warning message is expected since i686 has CONFIG_OF enabled and the machine used doesn't utilize OF.
