Hello,

This is still (since 10.10 as far as I remember) reproduced with my laptop HP Compaq 6730s (Radeon HD3430, 4Gb RAM, Ubuntu 11.10 x64) and the latest 12.6 driver.

Adding script
if [ "$1" == "suspend" ] || [ "$1" == "resume" ]; then
 swapoff -a
 swapon -a
fi

which disabled and then enabled swap on each suspend/resume to /etc/pm/sleep.d/ also has not helped.

It looks like swap usage system policy does not affect this issue.
(sysctl -w vm.swappiness = 0)

After some of resumes about 1.5GB can be swapped out when there is 2GB free system memory.

Thus the only solution for me I can see is to disable swap at all and track memory state as I really need "suspend" feature.

One point is still unclear for me: isn't swap usage completely under the kernel control?

Thanks
