Resume from suspend doesn't work for Lenovo T61 in Karmic (worked in Jaunty)

[Eero]

Binary package hint: pm-utils

Opening lid starts resuming and the computer shows password prompt briefly, but then goes to sleep again. After pressing power button the computer resumes normally.

Last time after opening the lid computer resumed normally, so maybe something has changed in the latest updates? I will report if this problem occurs again.

The problem occurred again. This time I tried to wake it up while on battery power.

I've had this happen to me as well. If I suspend while on power, then disconnect power and resume, what you describe happens. It starts up, but after a second or so, it goes back into suspend mode. Pressing the FN key brings it back. This only happens after disconnecting from power. If the system is suspended on battery and resumed on battery (or power) this does not occur. If the system is suspend on power and resumed on power this does not occur. This behavior did not happen in Jaunty.

Feels like a race condition, but I can't think where....
