I have an ubuntu 14.04 server, the server will be in a parking to manage it with a software.

When I turn ON ACPI, my server took more than 2minutes to boot, else it takes only 30-40secondes.

I need to have ACPI ON because when I push the power button it needs to send the request to shut down and not directly cut the power (as far I know it's ACPI who manage the power button).

To conclude, my server needs to have a boot time more acceptable and with the power button working.

You can find boot log: here

And bootchar log: here

I'm not able to read properly these logs, thank for help!

  • It's taking over a minute to mount the hard disk. Maybe the system is not shutting down cleanly and has to do a disk scan – PiedPiper Dec 11 '17 at 10:48
  • I reboot the server with, sudo reboot. Do it's wrong ? – user265326 Dec 11 '17 at 10:50
  • that should be ok if you wait till the disk is unmounted before turning off the power – PiedPiper Dec 11 '17 at 10:51
  • Yes, I didn't cut the power. The strange thing is if I disable ACPI, my system will boot in 30-40 seconds – user265326 Dec 11 '17 at 10:53
