Cannot hibernate Lenovo Thinkpad Reserve Edition

[keithbannister]

Hi,

I've got a Lenovo Thinkpad Reserve Edition with Ubuntu 10.10. Everything updated.
I'm pretty sure there's enough swap.
When I try to hibernate using the gnome 'switch' control on the top right. The screen goes to black screen, thinks a bit then resumes immediately.

Suspend works.

The second time I try, the black screen says:
"PM: Not enough free swap"


Ubuntu installed with wubi, which didn't have enough swap space. I had to add swap with swapon.

$ swapon -sf
Filename Type Size Used Priority
/host/ubuntu/disks/swap.disk file 261116 1988 -1
/host/ubuntu/disks/swap2.disk file 2097148 0 -2

My feeling the 'Not enough free swap' error is a phoney. I'm pretty sure there's enough free swap now, but I'm not sure which numbers to use here:

Here's a suspicious section of /var/log/messages during an attempted hibernate:
