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? -- Cheers, Luca.
