            Bug ID: 220855
           Summary: iwm crashes complete OS
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

          Reporter: marko.cupac at mimar.rs

Hi,

I am occasionally having a hard time with iwm driver on my ThinkPad T440, in a
way that I suffer frequent disconnects which require me to `service netif
restart'.

But today it crashed complete OS for the first time. Perhaps it is time to file
a PR, hopefully someone picks it up.

pacija at efreet-freebsd:~ % sudo freebsd-version -ku
11.0-RELEASE-p9
11.0-RELEASE-p10

pacija at efreet-freebsd:~ % sudo dmesg | grep 7260
iwm0: <Intel Dual Band Wireless AC 7260> mem 0xe0400000-0xe0401fff at device
0.0 on pci2

Here's excerpt from messages log:
