I use a Lenovo U31-70 with a Qualcomm Atheros QCA6164 Wireless Network Adapter using the
ath10k_pci driver module.
I recently tried to upgrade my Jessie installation to Stretch by altering my
/etc/apt/sources.list to point to the
stretch repositories, and then running
apt-get update and
apt-get upgrade. This ran for quite a while and got into a loop where the restart of
network-manager timed out, and finally hanged my system hard enough to make it non-responsive.
After hard reboot, the system booted up and connected fine to my wifi, but running any
apt-get operation finally ended up in the same state.
I decided to take drastic action; backed up my
/home and installed Debian Stretch with non-free additions from scratch.
apt-get works fine, but the system won't shut down cleanly. Sometimes I will get a black screen with network operations trying to finish but never succeeding.
[* ] (1 of 2) A stop job is running for Network Manager (4min 49s / 5min)
[* ] (2 of 2) A stop job is running for WPA supplicant (5 min 2s / 6 min)
If I loose a network connection, I'm not able to re-establish it or switch to another network.
# service wpa_supplicant stop
takes about two minutes to return and so does
# service network_manager stop
Has anyone else experienced trouble with network managing in Stretch? Is there anything I can do about this?
