I'm running Archlinux and have recently upgraded the following (at the same time):
- linux (5.0.13.arch1-1 -> 5.1.4.arch1-1)
- linux-firmware (20190424.4b6cf2b-1 -> 20190514.711d329-1)
Since then, Wi-Fi would frequently stop working. I'd have to disconnect and reconnect to get it working again (but that only lasts for a while).
I've tried downgrading linux-firmware to the known-working version (20190424.4b6cf2b-1) while keeping the kernel at 5.1.4, but that didn't help.
Using the older kernel (Archlinux's linux-lts, which is at version 4.19.47-1) seems to solve the problem - Wi-Fi is stable.
I've waited for a few kernel upgrades since then (now on kernel 5.1.5.arch1-2), but the problem persists.
This is on an HP Elitebook 850 G1 with an Intel(R) Dual Band Wireless N 7260, REV=0x144.
I'm providing debug data when running:
- Linux 5.1.5.arch1-2
- the debugging firmware for the 7260: iwlwifi-7260-17.ucode (`ethtool -i wlan0 | grep firmware` says: firmware-version: 17.3216344376.0)
Looks like the last time it happened, it crashed multiple times in a row (as evident from dmesg.log).

This is the first dump that got generated by the debugging firmware. There are 19 more that follow it (they all happened within an interval of 2 minutes).
