Workstations shutting down for no apparent reason (F8)

[Alain Cochard]

Hello.  I am running 40 workstations with 3 kinds of hardware, all
under fedora 8.  From time to time -- about once every 3 days -- one
of the machine (not always the same) shuts itself down.  Otherwise
they are running 24 hours a day every day. 

The excerpt of the /var/log/messages that seems relevant to me is
always similar to the following:

Nov 18 15:12:26 epgs16 acpid: received event "button/power PWRF 00000080

Thanks in advance for any tip on how to solve this problem.

Thank you very much Linuxguy and Roger.  About half of the machines --
the most recent ones -- have "instant off" in the bios.  I will change
the option and see if the problem remains.

No equivalent option in older hardware?

Has anyone some insight about the consequences of disabling acpi?

If you have instant off set in the bios, there are a number of motherboards
on which the power switch will pick up enough noise to send a proper off
signal even though no one is pushing the button...

The easiest solution is to not set instant off.

I am not an expert, but I think you can add the "acpi=off" option to the
kernel entry in grub.   That would stop it from shutting down the
workstation, but it would also disable other stuff...

If you have instant off set in the bios, there are a number of motherboards
on which the power switch will pick up enough noise (from the wires going to the 
power switch) to think it was send a proper off signal even though no one is 
pushing the button...

The easiest solution is to not set instant off.
