My Intel 7265 used to work flawlessly, but for the past week or two it
has seemed to be very unreliable. It's also throwing errors. I see
problems on firmware versions 16 and 21, although I haven't gotten the
warning and backtrace on firmware 16 yet.
I have:
iwlwifi 0000:3a:00.0: enabling device (0000 -> 0002)
iwlwifi 0000:3a:00.0: Unsupported splx structure

iwlwifi 0000:3a:00.0: L1 Enabled - LTR Disabled
iwlwifi 0000:3a:00.0: L1 Enabled - LTR Disabled
I just got this error on 4.7.0:

Shouldn't that cause packet loss, not actual stuck queues? Or is the
problem that the device literally can't transmit at all for 10 seconds
and the driver eventually gets sick of waiting? Could the driver
learn to detect this more sensibly, drop the packets cleanly after
some timeout, and maybe log a message about extremely high noise?

I haven't seem any of these problems on 4.8-rc yet. I'll keep you
posted if I do.
Hi Andy,
Sorry for the really long delay in replying. :(

This seems to be a recurring error with the AC-7265. :( We even added
an entry about it in our wiki:

We have a bugzilla entry with the queue stuck + NMI trigger:
https://bugzilla.kernel.org/show_bug.cgi?id=112931
Unfortunately nothing was found out by our firmware team regarding this
yet.

We also have an open bugzilla entry with similar WARNING:

So, first I'd recommend that you follow the recommended workarounds in
our wiki. If that doesn't help and you still want to try to help us
debug this, please open a bugzilla so we can track it more easily.
Sorry for the trouble you're having...
