Subject: iwl_mvm_add_new_dqa_stream_wk BUG in lib/list_debug.c:56

Hi,

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.

dmesg:

Is that a known issue? I currently have this with 5.1.5, are there patches in
the queue that may be candidates to stabilize my wireless again?

Greetings
Marc
