Red face Problem with Suspend/Hibernate option on Acer 3620 Laptop.


Hello,

I have installed Ubuntu 8.0 on ACER 3620 Laptop with 1.5GB RAM. Everything seems to work fine except the Suspend and Hibernate options. Its a clean install no dual boot.

When i select suspend, i get a serious of text messages and is stuck at Suspending console. and nothing happens, i press a key, etc, but the system doesn't come back. I have poweroff the laptop directly and power it on. I have insalled all the OS updates after installing the OS.

i noticed a error in these text messages.

582.008342 code: Bad EIP value
EIP [<f8bd7d30> 0xf8bd7d30 SS:ESP 00:f7571f28
end trace..

Please help
Avinash

That is a kernel crash
So your system may have some mis-behaving drivers during crash

Try moving to single user mode and use minimal drivers (remove the not-so-important using rmmod)
and try doing the suspend.

This seems to be a common problem with several different makes of laptop. I'm afraid I can't find a good solution, but many people have found that disabling the wireless card first (if there is a hardware switch on your machine) cures the problem. That's perhaps worth trying.

This is a common problem. There is an extensive post on the subject in the in Ubuntu forum here:

I don't even try to use suspend on any of my laptops.

I had a problem with suspend... my screen would come back extremely dark. Adding
Code:
Option          "VBERestore"          "true"
to my xorg.conf under your driver cured the problem for me. That may not help you in this instance, but it's helped me.

Thank you for your replies.

i also read that i need to disable my wireless network card. And not able to do that. The wireless card driver is not /etc/network/interfaces files, below is what is happening with the OS Log and this keeps repeating. The don't see any disable button in network graphics tool. How do i disable my wireless network card?

Do you think this is solved in Ubuntu studio?

Smile Solved!!

Hello all,

I tried everything you all said but nothing happened.
When i closely read the system log, i noticed that, the OS was probing the wireless adpater continuously. So, i installed the wireless adpater using the GUI tool and everything worked, both Suspend and Hibernate works!!

Could you give a step-by-step description of exactly what you installed and how you did it? I think that could help many other people.

Okay.

I am using Acer 3620 Laptop with 1.5GB RAM.

I did a clean install of Ubuntu 8.04 CD. I made sure internet was available during install. I installed all the required OS updates/upgrades after installation.

The OS was prompting for the installation of the inbuilt wireless NIC, which is a broadcom B43 wireless driver. But, the Hibernate and Suspend wouldn't work. It would go into command mode and get stuck. When i searched the forums, most of it told me disable the wireless adapter, so i was figuring it out. But, when i looked at the System log, i noticed that the OS was probing for the wireless adapter continuously. Thats when i decided to install the driver!! After which the suspend and Hibernate options started to work!

This may not be the case with everybody.
Hope this helps.
Avinash
