I can reproduce this. It happens MOST OFTEN when hardware switch is OFF when going into standby. Basically:
(1) Switch hardware wifi switch off (2) Go into standby (3) Come out 90% of the times, wireless is not restored. eth1 shows up with no wireless extensions. I've attempted to kill, remove run-lock, and restart ipw3945d. No luck. Flick hardware switch -- nothing happens. But killing the daemon, removing the pid lock, rmmod ipw3945, and modprobe ipw3945 does restore operation. This has not happened before Feisty. ** Changed in: linux-source-2.6.20 (Ubuntu) Status: Needs Info => Confirmed -- IPW3945 unable to restart after suspend https://launchpad.net/bugs/91645 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
