Can you please try this: https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/commit/?h=for-john&id=f6b129527ca15bae29ffb9417ddaa1c9d99ffc5d Thanks
Josh, please apply above patch. It remove the WARN_ON that is reported and it also should fix related problems. Since those problems are not easily reproducible (happen after 2 weeks of uptime) I prefer just to apply the patch instead of preparing test kernel. If problems will still happens, bug should be reopened.
Added to all branches. Thanks!
