Automated suspend/resume testing is grumpy about iwlwifi, because
iwlwifi dmesg's with the words "Invalid" and "Failed", which our
heuristics highlight as issues a human should review.
If this is normal, can you delete the messages? If this is a failure,
can we fix it?
thanks,

I had been looking a bit at either removing messages with level
KERN_ERR or or fixing the underlying issue. With the plan to get clean
runs with regard to kernel log level at least. I didn't look for
specific keywords like "invalid" or "failed" though.
I believe The debugfs one is an actual bug (harmless though) for which
a patch should be posted soon.
I don't remember seeing the "WRT: Invalid buffer destination" message.
Will need to take a closer look, but quite likely it should just be
hidden unless the IWL_DL_FW debug flag is set (i.e. use IWL_DEBUG_FW).
