Description of problem: After my Dell XPS M1330 (Intel 10/100 ethernet, iwl4965agn wifi) running Fedora Core 13 x64 with kernel 2.6.33.8-149.fc13.x86_64 resumes from suspend, sometimes networking doesn't come back up. The GNOME NetworkManager applet shows "Enable networking" unchecked and usually greyed out. If it's not greyed out, checking it has no apparent effect; it remains unchecked, wifi doesn't come back up, etc. When NetworkManager is in this condition, nm-tool reports "State: asleep" . The underlying hardware still works fine. I can use iwconfig and ifconfig to get a wifi connection set up, then dhclient to obtain an IP, just like in the pre-NM days. Restarting NetworkManager appears to restore it to functionality, and it connects to wifi if it becomes available. This is a fresh Fedora Core 13 x64 install on a machine that was previously running Ubuntu 10.04 (32 bit). I didn't see this issue under Ubuntu, but it was running nm 0.70 whereas fc13 has 0.8.1 . How reproducible: It's intermittent and I haven't been able to reproduce it on demand. It occurs on something like 1/5 of resumes. I suspect a race condition somewhere.
This probably isn't related to bug 573799 or bug 589108, as they appear to relate to NM state tracking after the machine is suspended, then loses power. In this case the machine resumed normally, but NM didn't seem to "notice" the resume, thinking the system was still suspended. Logging attached.

Oh: Having failed to provide the obvious: NetworkManager-0.8.1-4.git20100817.fc13.x86_64
Confirmed here. NetworkManager-0.8.1-4.git20100817.fc13.x86_64 Although, resume from hibernation (instead of standby) seems to work.

Duplication of bug #629783?
I'm also encountering this. It's only been happening for a couple of weeks now, on both my and my partner's laptop. I'm trying out NetworkManager-0.8.1-6.git20100831.fc13 now to see if it improves the situation.
Take a look to my comment #10 to bug #627365. The workaround there works for me to fix the issue.
The issue not waking up has been fixed in NetworkManager-0.8.1-6.git20100831: NM don't rely on pm-utils now: see https://bugzilla.redhat.com/show_bug.cgi?id=627279#c13 There is a workaround to the issue - adding '--print-reply' to /usr/lib64/pm-utils/sleep.d/55NetworkManager: see https://bugzilla.redhat.com/show_bug.cgi?id=627279#c10 The issue of grayed checkboxes has been fixed by NetworkManager-0.8.1-6.git20100831 as well (bug 627365)
I'm not encountering this anymore with the current NetworkManager packages.
Thanks for reporting! I close the bug then.
Sorry, but with F14 and nm-version NetworkManager-0.8.1-9.git20100831.fc13.x86_64 I have the problem again. I'm not sure, but I think, it's only on hidden networks (I can test, if you want). With F13 I didn't have the problem.
