CC'ing iwlwifi maintainers to get some attention for this issue.
I am experiencing the very same bug on a ThinkPad T480s running 5.1.6
with Fedora 30. A friend is seeing it on his X1 Carbon 6th Gen, too.
Both have an "Intel Corporation Wireless 8265 / 8275" card according to
lspci.
Notably, in all cases I've observed it occurred right after roaming from
one AP to another (though I can't guarantee this isn't a coincidence).
Here is the dmesg output from my machine:

on my primary notebook, a Lenovo X260, with an Intel Wireless 8260

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.
