Suspend takes very long, more than 20mins

[Rohan Dhruva]

This could be a linux kernel or a pm-utils bug. However, from the last few updates, at least from Linux ubuntu 3.13.0-8-generic, suspend is taking a very long time. It takes over 20mins. The "suspend" indicator keeps blinking.

First few times, I decided to power off the system thinking it's some other failure. However, yesterday I noticed that the system actually does suspend: it just takes a lot time (20+ minutes). It didn't take more than 2-3 minutes in the past.

I have changed my pm settings to do a hybrid sleep when "sleep" is selected. I will post the config file soon.

Thanks for reporting this bug. Just to be clear - is the laptop in fact 'suspending' or 'hibernating'? Do you have this same problem if you remove the custom configuration for hybrid suspend?

[Rohan Dhruva (rohandhruva)]

The laptop is doing a hybrid sleep: writing to disk and then sleeping to RAM. It does not happen when I revert to the default suspend-only mode.

Also, I notice this happens only when my RAM utilisation is high. I don't know if that is a bug or intended because my swap partition is small.
