[fix] iwlwifi - Failed to load firmware chunk!

Hi!

Had trouble with getting my wifi adater (iwlwifi module) working after the latest kernel update (4.20.3-arch1-1-ARCH). Since I managed to fix it with a kernel option, I thought it might be worth sharing my solution.

First, check that the problem is indeed with the firmware:

dmesg | grep firmware

Look for: "Failed to load firmware chunk!"

To solve the problem (temporarily) - given that you are not using PCI pass-through - simply add

intel_iommu=off

to your kernel boot-options.

Hope this can help someone running in to the same problem.

EDIT: Using the latest kernel (4.20.7) this will create the issue instead of solving it. So, the solution is to revert the changes, and wifi will once again work.
