Interesting that you found a good way to reproduce this.  Does it happen
everytime you suspend while monitor mode is enabled?

We have seen a similar case here:

https://bugzilla.kernel.org/show_bug.cgi?id=192691

To use monitor mode you need to use amsdu_size=3 in iwlwifi module
parameters.  Check my comment #15 there.

Can you try this and add your results in that bug report so we can track
the progress?
