Sure enough, there are the errors.
[   10.346886] stmmac_platform: module license 'unspecified' taints kernel.
[   10.384361] stmmac_platform: Unknown symbol devm_kmalloc (err 0)

 It's possible rc4 has the fix, this is rc3
4.2.0-0.rc3.git3.1.fc23.armv7hl

I look forward to testing it on next weeks image, or whenever rc4 hit's the
