Hello, I'm also still experiencing this issue on 5.1.15. It's making it
very difficult to use my work laptop in my office, since it has many
access points and frequently has to reauthenticate. I hit this bug 1-3
times per day, and the only way to fix it is a hard shutdown. Has there
been any effort to identify and/or fix the cause?

on my primary notebook, a Lenovo X260, with an Intel Wireless
8260
(8086:24f3), running Debian unstable, I have started to see
network
hangs since upgrading to kernel 5.1. In this situation, I cannot
restart Network-Manager (the call just hangs), I can log out of
X, but
the system does not cleanly shut down and I need to Magic SysRq
myself
out of the running system. This happens about once every two
days.

The issue is also present in 5.1.5 and 5.1.6.

Almost a month later, 5.1.15 still crashes about twice a day on my
Notebook. The error message seems pretty clear to me, how can I go on
from there and may be identify a line number outside of a library?

Greetings
