Bug Description
Binary package hint: network-manager
network-manager version 0.6.3-2ubuntu6 (edgy)
linux-image-
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?
