Just a few updates which may be of use to anyone else having the same
issues...
1). As this issue persists without a truly good solution, it may be a
good idea to simply replace the wifi card with, say, an Atheros one
which works better. You can find them relatively cheaply on ebay.

Seth, you are right, I didn't check it careful enough.
Ben, you probably need to file an upstream bug report.
You can also iwlwifi-core [1] as a last resort. It has some non-
upstreamed fixes.

Zesty already has the latest 7260 firmware (revision 459231), and
according to the attached CurrentDmesg.txt that's what being using:
[8.000329] iwlwifi :01:00.0: loaded firmware version 17.459231.0
op_mode iwlmvm

There's a new 7260 firmware, can you try it?
1. Download https://git.kernel.org/pub/scm/linux/kernel/git/firmware
/linux-firmware.git/plain/iwlwifi-7260-17.ucode
2. Put 'iwlwifi-7260-17.ucode' to /lib/firmware
3. Reboot.

Issue definitely persists on 4.11/upstream. I came across an interesting
output in dmesg which may explain why bluetooth works while the WiFi
doesn't:
[17326.525545] iwlwifi :01:00.0: Could not load the [0] uCode section
[17326.525697] iwlwifi :01:00.0: Failed to start INIT ucode: -5
It took less than 10 minutes of testing for the issue to come back up
again under 4.11-rc7. Definitely NOT fixed upstream. I'll keep testing
and see if I find any other unique behaviours/error messages. Thanks
again, let me know if there's anything I can do!

Some additional notes after testing for a while...
The crashing behavior doesn't occur consistently in the same way.
Sometimes the Bluetooth crashes with the Wifi, while sometimes it
recovers fine and continues to work while the Wifi doesn't. In addition,
it seems that the Wifi crash breaks
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.11
Dell xps 9333, same problem.
