acpi shutdown bug, is 'sudo shutdown now' safe?

[Jean]

Hi,

I have this pentium 2 as file/webserver and upon starting hardy I get a message about the bios too old for proper acpi support.
The machine will not shutdown properly, it keeps displaying the hardy splash.
I didn't tinker with any boot option yet.

I would like to know if it is safe to just do a 'sudo halt', or 'sudo shutdown now' from the console and then flip the power button.
If this really halts everything, shuts down the harddisks properly, I could very well live with that.

Thanks.

I'm not totally sure about that,, but you can put

acpi=no

at the end of the GRUB entry

kernel		/boot/vmlinuz-2.6.24-20-generic root=UUID="bunch of numbere" ro quiet splash

(or something similar to that line). That should take care of the

message about the bios too old for proper acpi support

. It might also help on the shut down process. Not totally sure, but that's what I've seen posted around the net.

Call me paranoia but I'm really a beginner. So I want to mess around with systemfiles as little as possible. Who know after putting that line in menu.lst it will not boot anymore and I would have to mess with live cd's.
So if I knew that it's safe to flip the power button after sudo shutdown now I will go for that.
For the time being that is, at the moment I have lots of work to port my file/webserver over to ubuntu os.

Try

sudo shutdown now -h

No guarantee ....
