Dell Inspiron 510m - tasks not stopping on Hibernate

[Aaron Whitehouse]

Here is a hibernation problem with Matthew's favourite brand of laptop. Hibernation is infinitely better in Edgy, since this morning (20/09/2006), than it was in Dapper or the Knot 3 CD.

About 1 in 5 times, however I am getting:

and the machine is immediately re-awaking.

Any information that you need, let me know.

[Aaron Whitehouse (aaron-whitehouse)]

Here is the complete extract from my syslog for the period immediately preceding telling the machine to hibernate until after it was fully awake again.

[Aaron Whitehouse (aaron-whitehouse)]

My machine just failed in this way. If I try and hibernate again, the same thing keeps happening. This suggests to me that it isn't just intermittent. I can't figure out what could be causing it, however, so any help would be very welcome.

[Gregory Oschwald (osch0001)]

This happens on my Thinkpad x60s when using Upstart. I do not experience this problem when using sysvinit instead.

[Aled Griffiths (aled-griffiths)]

I can confirm that this happens on my Dell Inspiron 510m, with Edgy. It happens occasionally when closing the lid - but *appears* to happen more often when I use the Fn+Esc (Suspend) Hotkey.

[Aled Griffiths (aled-griffiths)]

I forgot to mention that I have configured gnome-power-manager to suspend when the lid is closed.

[Aaron Whitehouse (aaron-whitehouse)]

Marking as confirmed based on the comments above.

[Stefan Daniel Schwarz (Wolfram Ravenwolf) (stefandanielschwarz)]

I'm occasionally experiencing this problem with my ThinkPad X60s: Trying to suspend fails with the message "stopping tasks timed out after 20 seconds", then it tries to resume, but the display isn't turned on.

I know there's a seperate bug reported about the display not being turned on when resuming, related to s3_bios support, but when suspending succeeds, resuming will work properly as well. Only when it fails to suspend will the display stay turned off.

So I believe that fixing suspend will automatically fix resume, at least on my laptop.

(I also reported this to Bug #70602 - not sure if/how it might be related to this issue!)

[Nanley Chery (nanoman)]

Is this still a problem in the latest stable of Edgy or Feisty? or the development release of Gutsy?

[Aaron Whitehouse (aaron-whitehouse)]

I haven't had it on Feisty or Gutsy (that I can remember), so feel
free to close it. I will reopen it if I have the problem again.

[Nanley Chery (nanoman)]

Your wish is my command.
