** Description changed: - After upgrading pm-utils from 0.99.2-3ubuntu5 to 0.99.2-3ubuntu6 my - iwl3945 wireless driver no longer worked after suspend-and-resume. A - full reboot was required to make it work again. - https://bugs.launchpad.net/ubuntu/+source/udev/+bug/208103/comments/5 - suggested a solution that seems to work: removing /etc/udev/rules.d/70 - -persistent-net.rules and rebooting so that it was regenerated. I am - leaving this bug open so that it can be evaluated by udev (duplicate, - invalid, or a genuine problem with some earlier versions of this file). + The logic in udev according to /etc/udev/rules.d/70-persistent-net.rules seems to have changed: + Old lines look like: + # PCI device 0x10de:0x0057 (forcedeth) + SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:0f:ea:8c:2d:36", NAME="eth0" + which causes udev to add new lines like the following after suspend/resume (module unload/reload): + # PCI device 0x10de:0x0057 (forcedeth) + SUBSYSTEM=="net", ACTION=="add", ATTR{type}=="1", NAME="eth2" + + After removing 70-persistent-net.rules and rebooting, the following line gets created: + # PCI device 0x10de:0x0057 (forcedeth) + SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0f:ea:8c:2d:36", ATTR{type}=="1", NAME="eth0" + + The old entries are missing an ACTION and ATTR{type} attribute, which + seems to cause udev to add the extra line and therefore renaming the + interface somehow. + + ORIGINAL DESCRIPTION: + After upgrading pm-utils from 0.99.2-3ubuntu5 to 0.99.2-3ubuntu6 my iwl3945 wireless driver no longer worked after suspend-and-resume. A full reboot was required to make it work again. https://bugs.launchpad.net/ubuntu/+source/udev/+bug/208103/comments/5 suggested a solution that seems to work: removing /etc/udev/rules.d/70-persistent-net.rules and rebooting so that it was regenerated. I am leaving this bug open so that it can be evaluated by udev (duplicate, invalid, or a genuine problem with some earlier versions of this file). System info was attached to bug 204040 (all with the failing pm-utils 0.99.2-3ubuntu6 and /etc/udev/rules.d/70-persistent-net.rules file installed): $ uname -a Linux gertrude 2.6.24-12-generic #1 SMP Wed Mar 12 23:01:54 UTC 2008 i686 GNU/Linux Output of "lspci -vvnn": http://launchpadlibrarian.net/12935525/lspci-vvnn.txt Output of dmesg immediately after boot (no attempt at suspend at this point) http://launchpadlibrarian.net/12935528/dmesg-afterboot.txt Output of dmesg after resuming from suspend: http://launchpadlibrarian.net/12935535/dmesg-afterresume.txt Output of dmesg after resume and after running "modprobe -r iwl3945 && modprobe iwl3945" as root: http://launchpadlibrarian.net/12935544/dmesg-aftermodprobe.txt Other possibly relevant info: I am using Network Manager to manage the wireless connection, version 0.6.6-0ubuntu3. + + WORKAROUND: + 1. sudo rm /etc/udev/rules.d/70-persistent-net.rules + 2. Reboot + /etc/udev/rules.d/70-persistent-net.rules should have been regenerated correctly.
