iwlwifi crashes during moderate traffic

[John]

iwlwifi crashes and locks up my computer whenever I visit a website with a lot of images, try to install a large package with apt, or just about anything that requires a moderate amount of bandwidth. This happens somewhat randomly; some days I run into it constantly, and some days I can go maybe half an hour without it crashing.

I'm seeing some similarities with the bug below, although I'm not 100% sure it's the same issue. Is there any chance of backporting that fix from 5.5?
