Computer sometimes wakes up immediately after suspend

[Gorka Navarrete]

My laptop generally suspends without problems but sometimes wakes up immediately after suspend.

When it fails, you can see the screen going dark as if it were suspending and an instant after the computer wakes up (screen unlocked).

This is with a Lenovo Y500 in a recently upgraded 13.04 (from 12.10, where this problem also occurred).

I am attaching inline the log section for a failed suspend try.

In brief, when I try to suspend, the computer goes down and then immediately up.

A device (eth2?) seems to be failing to suspend.

Not sure if this is related to some problems this model (Lenovo Y500) has with the wired connection not working.

Any help would be greatly appreciated.
