Hello altogether, I am affected too. From time to time the same error
occurs, showing the "queue stuck" and "Hardware restart" messages, while
WiFi-connection is not working. It happens then in a loop. I am not
running Ubuntu, I am running aptosid with "4.10.0-8.slh.1-aptosid-amd64
#1 SMP PREEMPT aptosid 4.10-13 (2017-04-06) x86_64 GNU/Linux". So this
could be a *linux-generic* problem:

I have this issue since several releases, but I don't remember exactly, when it
started.
***
But today I got aware, of how to "fix" it... I was running a USB3-connected
harddisk,
and when I disconnect it, problems immediately gone!!!
***
Stalled downloads continue, WiFi is working flawless again, as soon the
drive is gone.
And as soon I connect USB3-HDD again (just connect, you even don't have
to mount a filesystem, the WLAN-error-loop gets me again!
So I see a connection toe USB3-hardware-internals? Maybe a hardware-
problem, triggered somehow, or something with USB-stack... but I don't
understand, how it can influence WiFi.
I am running Linux on a Dell Latitude E7450. I have some kernel-
parameters in use, maybe they have influence too, so for your
information:
$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-4.10.0-8.slh.1-aptosid-amd64
root=/dev/mapper/MyNiceNode-lroot ro i8042.nopnp atkbd.reset pcie_aspm=force
nmi_watchdog=0 libata.force=noncq video=SVIDEO-1:d
The WiFi-card is a:
$ lspci|grep -i wire
02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
And in more detail with lshw-excerpt:

The USB3-HDD is directly connected to a USB-interface at the back of the
laptop, via a IcyBox IB-AC703-U3 interface.
When I run (the same) HDDs within a HardiskDock connected via esata, I don't
have WiFi-restarts either (Latitude E7450 sadly lacks direct esata-ports, so I
have a DockingStation to make use of esata).
Maybe someone can confirm having connected some USB stuff to the systems, when
the problems pop up?
And (maybe) not directly connected to this issue, but I experienced more
weird USB(3)-related phenomens, I may describe later, but all resulting
in bus-resets so devices are "gone". I miss my esata, that was stable
with multiple-disk-IO.
However, I hope, I can help with my input!
Regards
