    `sudo reboot` doesn't reboot

    Hi,

    I'm running Ubuntu 6.06.2 on my server. Every time I do `sudo reboot`, everything is shutting down, I can see "Will now reboot", but it doesn't reboot.

    However the computer doesn't seems completely powered off. A led is turned on. In order to complete the reboot, I need to hold the "power" button for 5 seconds, then push it again to boot the computer.

    I've passed each option of the BIOS one by one, but nothing seems related to my problem. (Maybe I missed it....)

    Here is the output when I try to reboot :

    Code:
    Apr 25 22:19:30 jogger shutdown[4499]: shutting down for system reboot
    Apr 25 22:19:30 jogger init: Switching to runlevel: 6
    Apr 25 22:19:32 jogger mysqld[3647]: 080425 22:19:32 [Note] /usr/sbin/mysqld: Normal shutdown
    Apr 25 22:19:32 jogger mysqld[3647]:

    Apr 25 22:19:35 jogger mysqld[3647]: 
    Apr 25 22:19:35 jogger mysqld_safe[4588]: ended
    Apr 25 22:19:38 jogger kernel: Kernel logging (proc) stopped.
    Apr 25 22:19:38 jogger kernel: Kernel log daemon terminating.
    Apr 25 22:19:38 jogger exiting on signal 15

    Any hint where I can search to find the problem ?


    Thanks,
    Mathieu

    I know it doesn't really answer the reboot command problem, and it might even be aliased, so this might be pointless to try, but does
    Code:
    sudo shutdown -r now
    have the same result. I have had similar problems w/ reboots/shutdowns on my laptop running hardy, but I'm away from it right now

    Same problem with `sudo shutdown -r now`.

    Has this computer always done this?

    Try looking at power management in the BIOS.

    Also try upgrading the server to latest release.

    Re: `sudo reboot` doesn't reboot

    I'm having the same issue. I'm running the current release of Ubuntu Server (8.04 that I downloaded less than a week ago)...the 'sudo shutdown -r now' command begins the shutdown process but the system hangs after:

    *Will now restart
    [ 73.409331] Restarting system.

    I don't see anything in my BIOS that might be related, although I did try flashing to the newest version to try and fix this issue...

    It's a bit frustrating because I can't do much remotely if any time I need to reboot, it hangs...

    Update: the halt command works just fine...

    SOLVED: I turned the Dual Core option in my BIOS to Off

    could be related to the "reboot=b" issue.

    Re: `sudo reboot` doesn't reboot

    i have just the same problem with my box running ubuntu desktop 9.04
    i log in through ssh, then when i try to 'sudo reboot', first everything seems fine - i get the usual "i will now restart" stuff from the machine but it never starts again

    BUT what is different in my case, i used to reboot it this way - through ssh - and it WORKED, but a week ago it started to "stuck" in the reboot sequence

    this is a bit frustrating, because i have to administer the poor thing, but i'm 400 km away, so the go-there-push-the-button method is not so reassuring, because i have to wait, until someone get there...and i usually administer this one during nights..

    when i got someone there, i was told that the box is acting like turned off (monitor -no signal from graphics card, i got dropped from ssh during the shutdown sequence), but all the fans were running (and probably the leds were on too..)
    then a had my man push the power button, and the box started booting, like it was actually off...yeah, probably it forgot to turn the fans off... :-/

    so, i have no idea what is going on, nether can i check it out on the spot..
    i would really appreciate some advice - particularly, if it can be done through ssh..
    thx beforehand to anyone who tries..

    Re: `sudo reboot` doesn't reboot

    around the time it happened, i was just updating packages, installed gdesklets (box uses gnome) and played with X forwarding through ssh
    could any of those invoke the problem at hand?

    i tried to 'sudo reboot' when someone was logged in - no problem before, stuck now - and to first log out the user, then reboot - same. stuck.

    anyone? any idea?

    in the meanwhile, i read through the linked bugreports and the box has MSI or ASUS motherboard - none of the mentioned vendors - and their problems seemed constant, but my machine just started to act wierd..

    I am aware of some users reporting a hang on shutdown or restart that is somehow connected with wifi cards, but can't recall a suitable link at the moment.....
