Sleep/Suspend stopped working

It might be helpful to attach the output of lspci -v and uname -a . This is most likely a kernel bug...

I just updated everything to latest versions and sleep is working again. However hibernate still results in "Inconsistent disk structure" error. What's weird is that when I choose "rescue" mode the hibernated session will be resumed correctly.

I also wanted to note that sleep works great when I choose it from menu. Clicking sleep button on laptop will work just as good, but after wake-up gnome-power-manager gives notification "System failed to suspend", which is obviously wrong.

You might want to try the attached patch, as this is what redhat use. I'm going to commit something similar to gnome CVS today.

Richard

thanks richard. i've put this into our 2.13.93 package

Fixed in 2.13.93-0ubuntu1

Everything stopped working again after. It was ok in flight4, then broken, then fixed and now it is broken again.

Laptop turns to sleep ok, but then doesn't wake up. Screen stays black and disk activity led is on permanently, although no disk moves can be heard.

Suspending doesn't work at all. I have to turn it off manually.

I'm fairly confident this is an acpi-support or a kernel bug. The acpi-support guys should be better placed to help you

I found what is causing problems. It's the bluetooth module. When it is turned on sleep/hibernate will fail, when off everything work reliably (so far).

Is there a way to fix/workaround this?

Could you check if the machine does *finally* hibernate? I have seen the IDE LED being on permanently (again, no sound of any physical activity), but the machine didn't actually turn itself off (after about 5minutes of having left it alone).

When I enable bluetooth the situation is as follows:

1. Sleep

Notebook goes to sleep, but doesn't resume. There is some disk activity for a while, power led stops flashing, but computer is totally unresponsive. It's not just that screen is blank, notebook is literally frozen.

2. Hibernate

Hibernation doesn't work at all. Desktop blanks, there's some audible disk activity for a while, some noises in speakers and then nothing.
Notebook doesn't turn off and disk activity led is on, altough disk isn't doing anything. I have to turn it off by force and always get some serious problems with filesystem after that. Nothing lost yet, reiserfs always survives, but last time I needed to 2 reboots to get machine running again.

If there's some techical info I can provide, please tell me. I wanted to find out what bluetooth chipset it actually is, but haven't found anything in dmesg nor /proc.

Hi Łukasz, please could you try leaving the laptop a *really long time* (eg. 10-15minutes) and see if it does eventually complete the hibernate - you can tell because it will have turned itself off.

The internal bluetooth dongles are normally USB. Which can be viewed with:

  $ lsusb

Yes, notebook does finally hibernate after around 10 minutes. What worries me is that it worked immediately without bluetooth on few days ago, now it will take 10 minutes too.

My BlueTooth dongle is:
Camridge Silicon Radio, Ltd Bluetoot Dongle (HCI mode)

Is hibernation meant to work if swap partition is 512MB and whole ram (512) and half of swap is used? If not how can I set up seperate partition for hibernation purposes only?

Resume should work with the 2.6.15-20 kernel that's just been uploaded. Please open another bug for the problem with the slow hibernation.
