[Bug 655413] [NEW] NetworkManager: page allocation failure. order:3, mode:0x4020

[Phillip Susi]

Public bug reported:

After resuming from suspend today, network manager was showing the no
connection, no wireless signal, which was odd since I am on a desktop
with no wireless card.  I checked dmesg and it seems that there had been
a kernel OOPS in network manager:

Restarting tasks ... done.
