Public bug reported:

Binary package hint: acpi-support

I'm running Ubuntu server 8.04.1 on my laptop and controlling my iwl3945
wifi card via a "wpa-roam" configuration as documented in wpa_action(8).

interfaces(5) configurations that use wpa-roam do not shut down the
interface completely when stopped; instead they leave wpa_supplicant
running and only shut down the virtual interface for whatever network is
currently associated.  wpa_supplicant can't cope with suspend-to-ram; it
needs to be killed before suspending and restarted on resume.  acpi-
support seemingly expects this to be taken care of when it shuts down
the network interfaces.  In this case, that assumption is violated.  As
a result, my wifi card doesn't work after resuming.

I've worked around this by adding a new script to /etc/acpi/suspend.d
that runs right after 55-down-interfaces.sh and kills wpa_cli and then
wpa_supplicant, but this is rather hackish.  There ought to be a better
way of dealing with this.

See also #83959.
