Description of problem:
Loading batman-adv module gets oops
Version-Release number of selected component (if applicable):
Steps to Reproduce:
kernel oops - but module still seems to work fine. Kernel is tainted, which interferes with reporting other kernel bugs.
kernel-4.2.8 does not have the problem

initial oops that tains kernel
Sorry, this was on 4.3.3-301. I'll check 4.3.4 soon.
I reported this upstream.

batman-adv oopses with kernel-4.3.4-300+debug
Fixed with kernel-4.3.5-300.bz1303270.fc23.x86_64
Hm. I find that surprising. So with the single patch added and batman-adv loading, the oops goes away? If so, that's great news but I'm not sure why it would matter.
I haven't tested 4.3.5 without the USB wifi leak patch, so maybe something in 4.3.5 fixed it. However, maybe the oops is related to the USB wifi leak? As batman-adv was being used with the USB wifi.
I'll test with 4.3.5-300 (without leak patch) when I get a chance.
I'm on 4.4.2 now, and the oops is still gone. I don't think I'm going to go back to 4.3.5. Closing with "current release".
