Comment 11 for bug 61405

I confirm this: Edgy up to date has the same problem for a Thinkpad T60.

The sleep and hibernate sometimes work, and most times don't. Rather inconsistently. I have noticed that sometimes my swap partition is not on at all, I have to manually go to gparted and right-click and "swapon". Then 'top' correctly reports the swap. It's weird that in dmesg it says:

[17179653.888000] Adding 4425868k swap on /dev/sda7. Priority:-1 extents:1 across:4425868k

and later on in the boot messages I see that "mounting swap partition" reports "ok". But the swap is never on.

Even when manually activating swap, sleep and hibernate fail most of the time.

In thinkwiki.org there is a user reporting that disabling the powernowd (which controls CPU frequency scaling) allows for sleep to work. I've tried, and results are the same or worse: sleep works very little times.

A related issue is that when sleep works, sometimes it takes about 5 seconds, and most others something like 30 seconds. Independenlty of the number of open programs.

This little bug (when compared to an entire OS) makes ubuntu look very bad.
