wireless interface inactive after Suspend

Bug #79677 reported by Chris Conway
Affects Status Importance Assigned to Milestone
linux-source-2.6.20 (Ubuntu)

Bug Description

Binary package hint: network-manager

network-manager version 0.6.3-2ubuntu6 (edgy)
linux-image-2.6.17-10-generic version

Every now and then, when I come back from suspend, the wireless connection (driver ipw3945) is not re-activated. The radio indicator isn't lit and "Enable Wireless" does not appear in the applet menu. Removing and re-starting the driver module succeeds in re-activating the interface. I.e.,

rmmod ipw3945
modprobe ipw3945

The radio indicator flickers back on, the "Enable Wireless" option comes back (already selected), and the interface comes up.

Here's the wireless adapter info from lspci:
00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01)
0b:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

This is a bug in acpi-support, and not in network-manger. NM doesn't have anything to do with loading modules.

The issue appears to be that the module (or the regulatory daemon) doesn't properly support suspend. Perhaps adding it to the suspend blacklist might help?

RE: This bug being a duplicate, I would note that I am not having problems with boot/reboot at all. The problem is only with the module not loading on resume after suspend.

This only pops up intermittently, so I haven't had a chance to try any suggested solutions yet. Can someone post a more specific pointer to the "suspend blacklist". Google is utterly failing me on that. There's no mention in the marked duplicate bug, either.

Since this has be re-assigned to acpi-support, I'll add:
acpi-support version 0.90
acpid version 1.0.4-5ubuntu4

Pressing the "wireless kill" key after Resume doesn't help.
