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: ---
Component: wireless
Assignee: freebsd-wireless@FreeBSD.org
Reporter: marko.cu...@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@efreet-freebsd:~ % sudo freebsd-version -ku
11.0-RELEASE-p9
11.0-RELEASE-p10
pacija@efreet-freebsd:~ % sudo dmesg | grep 7260
iwm0: <Intel Dual Band Wireless AC 7260> mem 0xe0400000-0xe0401fff at device
0.0 on pci2
