[pkg-wpa-devel] Bug#814517: wpasupplicant: Unstable connection after laptop suspend

[Buck Huppmann]

i'll just note that i have the same problem

i'm running stretch/sid with

acpi-support    0.142-8
acpid   1:2.0.28-1
ifupdown        0.8.16
isc-dhcp-client 4.3.5~b1-1
laptop-mode-tools       1.70-2
pm-utils        1.4.1-16
systemd 232-3
wireless-tools  30~pre9-12
wpasupplicant   2.5-2+v2.4-3+b1

whenever mine gets into one of these loops, i notice a lot of

Dec 11 21:37:04 runt dhclient[10038]: bound to 10.110.210.69 -- renewal in 19822 seconds.
Dec 11 21:37:04 runt systemd[1]: Reloading.
... wpa_action stuff ...

Dec 11 21:37:04 runt wpa_action[10186]: ifdown wlan0
Dec 11 21:37:04 runt systemd[1]: Reloading.
Dec 11 21:37:04 runt dhclient[10217]: Killed old client process

until i get the hysteresis check messages that seem to bring the madness
to an end

this is all i have in my /etc/network/interfaces, aside from lo:

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
        wpa-driver wext
        wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
 
# no id_str, 'default' is used as the fallback mapping target
iface default inet dhcp

i wonder if it has anything to do with

/etc/dhcp/dhclient-exit-hooks.d/timesyncd

though my DHCP server isn't providing any time servers.  i'm going to
rename it timesyncd~ so dhclient-script doesn't source it and see what
happens, anyway, since i don't need it
