I got the same error - it happens twice:

Kernel: 4.11.5-1-ARCH (upgrading now to 4.11.7, but i will try 4.12 RC)

[881346.853394] BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
[881346.853465] IP: gen8_ppgtt_alloc_page_directories.isra.16+0xd9/0x280 [i915]

But it's like once a week, i notice that it only happens (but not always) when i get full memory and it starts to swap (and that's like once a week on 16GB of ram, it gets full because of those electron app that after a while use even 1.5GB/app, so periodically i restart them to maintain low (under 8GB) memory usage.

Before (but probably still) on KDE whenever i got my memory full the plasma will just totally freeze until some app doesn't crash with OOM, but that takes a while until the swap is filled up or i kill some apps from console/ssh.

And other apps (like music playback, ssh) still works after i915 crash.
