lenovo freezes after resume

[Moritz Winter]

After I upgraded from 12.10 to 13.04 I'm getting in trouble after I wake up my Lenovo T400 from standby. The first 5-30 sec. my mousepointer starts to freeze up and then the whole system freezes. I found a walkaround that works most of the time:
Change to a virtual console CTRL+ALT+F1 as long as the mouse is still moving and type in some words and wait a few seconds. Then the system runs w/o further freezes. If I'm not doing this the system must be resetted hard.

Sorry I don't know why this is listed under the network-manager-applet, I didn't chose it intentionally but I reported my last bug for this package.

Status changed to 'Confirmed' because the bug affects multiple users.
