Howdy,
I currently rmmod iwlwifi before putting my laptop to sleep and reload it
when coming back. Arguably, it's maybe not needed, but from time to time
I hit this memory allocation failure below.
I realize it's likely a memory fragmentation problem, but I have 8GB and
plenty of 'free' space, so I'm hoping that somehow it can be defragmented
enough for module loading ot work?
My kenrel config options are here

It will typically fix itself and work again later.
Any ideas?
