ubuntu on acer aspire 5520G doesn't shutdown

[matteli]

My laptop (acer aspire 5520G) doesn't shutdown. It stop at "will now halt". At this moment, if i press 2 keys, it shutdown.
I have tried to launch kernell with acpi=force , noapic, nolapic but doesn't work.

I use Ubuntu 8.10 (64 bit).

I'm also using Ubuntu 8.10 64 bit on an Acer Aspire 5520 and can confirm this same issue.

Hi

I have the same problem.

I have been had this problem since I updated my system to Ubuntu Hardy Heron. Recently I am using Ubuntu Jaunty and I am having the same problem. The computer give all normal messages of the shutdown process but it doesn't power off.
When I was using Ubuntu 8.04 LTS I didn't have this problem.

I also attached some log files.

Yes, I experience the same problem since intrepid on an Acer Aspire 5520.
In intrepid I saw the "halt : unable to iterate ide devices .." error but it is not there on jaunty although the problem is still there.

You can check out this bug # 298402 as it may be the same problem. I still haven't found a solutions for this as it is kernel related and really weird issue.

You could try disabling the splash screen and power off looking at the output to see how far it gets.

For my notebook, this problem is fixed in Ubuntu 9.10.
I also have the wireless light blinking now.
