Hi,
I'm using a Shuttle DS57U for a server. It's a nice little box with 2 NICs, so quite practical. I'm using it in remote locations over a network connection.
I installed Arch in June and it worked perfectly. However, this week I did a full upgrade and since then, the Shuttle insists on going into suspend after 10 minutes of inactivity. I wouldn't mind it if it would turn of graphics etc, but it also turns off the NIC. I can wake it up by pressing enter on the keyboard, but obviously, I won't be able to do that when I install it headless somewhere in the field. An active SSH just hangs. If I don't have an active session, SSH to the Shuttle reports that it's down.
I spent a full day trying to stop the Shuttle from doing this. I assume it's going into an ACPI suspend state, S1 or S3. The Shuttle's BIOS is very limited: I can only set the suspend state to S1 or S3, so I set it to S1. I also tried disabling C states, EIST and other power saving options, but no difference.
Furthermore, I tried masking the systemd targets for sleep, shutdown, suspend and hibernate as suggested here: https://wiki.debian.org/Suspend. Doesn't make a difference.
I also tried booting with the kernel option acpi=off. The system refuses to boot then.
Next, kernel option apm=off. No difference.
Next, kernel option acpi=noirq. No difference.
Next, I added a script under /etc/pm/sleep.d as described here: http://askubuntu.com/questions/521620/p … ons-are-on. My script is called 01_always_keepawake, contains the shebang, an echo message and exit 1. The idea being that returning 1 should prevent a suspend at any time. But this also doesn't do anything.
I'm getting terribly frustrated, particularly because the Shuttle didn't go to sleep before. How do other people do this? Is it so unusual to have a server located remotely that you want to be able to access through SSH at any time?
Thanks for any help!
Peter.

Quick update. I reinstalled Arch on the Shuttle and it works again. The screen still goes blank after 10 minutes (which I like) but it doesn't turn off the network anymore. Still very strange that it should start doing this after a simple pacman -Syu. If anybody has any ideas what could've happened, that would be welcome.
