Topic: pm-hibernate cycling

Hi,
When I  try to pm-hibernate, my Novena laptop is cycling back to life. Excerpt from /var/log/message :

Can anyone help me to get my laptop hibernate ?

Thx.

Best Regards

Re: pm-hibernate cycling

In fact, I see that "SwapTotal:         32764 kB" (when doing grep SwapTotal /proc/meminfo). Is there any reason to have such a minuscule amount of swap on the default setup ?

Re: pm-hibernate cycling

That's your problem. Hibernate copies the ram state to swap, so you'll need it to be at least 4G. The default swap is on the SD card and is small because you don't really want swap on SD. You'll need to sort out your SSD and get swap going on there.
