cannot shutdown / reboot laptop on 9.04

[Dallco]

My Dell 1720 has the same problem on a fresh 9.04 64bit install.................

ACPI=force acpi=off did not work..

I was having the same problem. If the laptop's wireless card was "on" at shutdown, it would hang and I'd get that blinking cursor in the top left corner. If the laptop's wireless card was "off" at shutdown, no problems at all.

So here's how I fixed it ...

Abstract: Add a short script to the init.d directory that uses "modprobe -r" to remove the wireless driver. Then add symbolic links to that script in both rc0.d and rc6.d directories.

Details:

1. Open a terminal and become super-user (yeah, this is a bad security practice, but I'm too lazy to type sudo before everything).

su

2. Navigate to the init.d directory.

cd /etc/init.d

3. Touch and edit your new wireless shutdown script. I use "vi," but feel free to use "gedit" if you like.

vi killwlan

4. Add line(s) that "modprobe -r" your wireless driver module(s). In MY case, I remove both "ipw3945" and "iwl3945" modules. In YOUR case, you'll need to find out the module names being used by your wireless device.

modprobe -r iwl3945
modprobe -r ipw3945

5. Save the script and exit the text editor.

[ESC] :wq [ENTER]

6. Navigate to the rc0.d directory.

cd /etc/rc0.d

7. Create a link to your killwlan script.

ln -sT /etc/init.d/killwlan S16killwlan

8. Navigate to the rc6.d directory.

cd /etc/rc6.d

9. Create a link to your killwlan script.

ln -sT /etc/init.d/killwlan S16killwlan

10. Now try to shutdown or restart.

init 6

This worked for me. If it works for you, great! If not, sorry for having wasted your time. Good luck!

Good point! When I turn off wifi manually (pressing the button for wifi card), I can reboot/shutdown perfectly. I tried your solution, with "iwlagn" and "iwlcore" instead of your modules, but it doesn't work. Maybe I cose wrong modules. Is there a way how I could find out exactly which modules are connected with wifi card?
I tried "sudo lspci -v" and that gave me this:

...
05:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100
    Subsystem: Intel Corporation Device 1301
    Flags: bus master, fast devsel, latency 0, IRQ 2296
    Memory at f9efe000 (64-bit, non-prefetchable) [size=8K]
    Capabilities: [c8] Power Management version 0
    Capabilities: [d0] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable+
    Capabilities: [e0] Express Endpoint, MSI 00
    Capabilities: [100] Advanced Error Reporting <?>
    Capabilities: [140] Device Serial Number 12-6e-5d-ff-ff-ea-16-00
    Kernel driver in use: iwlagn
    Kernel modules: iwlagn
...

Thanks for any advice.

Edit: when i run "sudo modprobe -r iwlagn" manually before I actually click on shutdown, everything (I mean shutdown/reboot) works fine, so i expect my problem to be the location and linking of the script. I'll play around for a while and if I find any results, I'll post them here.

I foud the cause of the problem - i forgot to change file permissions to enable executing.

cd /etc/init.d/
sudo chmod 755 killwlan

Everything else is as hesapotman posted, except the kernel modules, of course.

I'm having the same problem on my System 76 Pangolin (panp4n). Will give this a try.

its an error in the boot sector, try a bios update

[lisati]

I too experience this issue.

If you press Ctrl+Alt+F7, does the last line say Deconfiguring network interfaces by chance?

Occasional similar problem on a Toshiba m200 laptop running 64-bit 9.04: seems to do pretty much everything it should and then when it's at the stage when you'd expect the power to go off, there's a blinking cursor at the top left of a blank screen. I haven't noticed any error messages, and the system seems to respond to Ctrl+Alt+Del by restarting the system.

BTW, using EXT3 in preference to EXT4

Update on personal situation: have a fresh install of the 64-bit of Ubuntu studio (that's what I got the laptop for, to help with video stuff when I'm out and a bout)
Seems to be hung on the "deconfiguring netowrk interfaces", which kinda makes sense: the networking on the studio edition seems a little weird, I can use the wired connection if I restart networking manually through the terminal, but the network manager (manually installed) reckons eth0 isn't managed!
Also have "killing all remining processes.... [fail]" and a few lines above, "Pidfile not found! Is jackd running?"

Thanks.



EDIT: grumble grumble where did I put my 64-bit disks?

Same for me. HP pavlion 6680ev

vi killwlan

I don't see a file "killwlan" in the /etc/init.d/ directory. I'm on Jaunty.

I don't know if this is a red herring, however, in another thread there are complaints that laptops will not shut down or boot up when the computer is running on battery power. When plugged in to mains power there is no problem.
