This is probably a kernel bug in Fedora 20; but we shouldn't be polluting the logs just because of the kernel being unable to read a file that it claims exists:
# ls -l /sys/class/net/wlp3s0/speed -r--r--r--. 1 root root 4096 Jun 28 07:41 /sys/class/net/wlp3s0/speed # cat /sys/class/net/wlp3s0/speed cat: /sys/class/net/wlp3s0/speed: Invalid argument
Looks like the code detecting network interface link speeds that Michal was adding recently caused this. Peter

Good to know; let's get that series reviewed and in for 1.2.6 then. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
