Public bug reported:
I am running Ubuntu 10.10, but this problem has been around since Lucid,
and maybe Karmic. I apologize that I don't know in what package the bug
lies.
When I resume my laptop (Thinkpad X61-t, 64bit) from suspend, the system
freezes either at the login screen or immediately after logging in.
During the freeze, I can move the mouse cursor, but neither clicking nor
keypresses have any effect, and animations (e.g. nm-applet's icon) also
stop. The system "thaws" (becomes responsive again) 10-20 seconds later.
My guess is that the freeze occurs while attempting to connect to the
wireless. Further, it may be when it attempts to a different wireless
network than the one it was on when it was suspended (as it appears the
bug does not occur when I suspend and resume in the same room (e.g. if I
try right now)). It also may be caused by something related to network
connections, as I occasionally have a responsive system while it is
connecting, then freeze AFTER nm-applet reports that I have connected to
a network.
I apologize for all the guesswork. I'd be happy to try and debug,
collect logs, etc., if someone could point me in the right direction.
