I've seen "scheduling while atomic" before on zfs, I wonder if iwlwifi needs a similar fix...
https://github.com/zfsonlinux/zfs/pull/8150
I haven't seen this message though from iwlwifi. 5 seconds after associating you might still be in the dhcp phase, so I'm not sure what kind of traffic you would be passing at that time.

I honestly have no idea. I built this system on JFS as a test.
Could this be related?
