Powermac G4 and G5 on UPS won't reboot with after power outage

[Mathias Breuninger]

Hi,

Either G4 (Digital Audio) or G5 (2GHz DP 2003) won't reboot after power outage.

The UPS is an APC SmartUPS 750 (SUA750I) with apcupsd port.

Both the servers have dev.0.pmu.server_mode=1 in /etc/sysctl.conf (putting sysctl variable definition in /boot/loader.conf has no effect).

I did a real power outage test: the servers halted as expected. I waited for the UPS "Grace Period", but they didn't boot.

I tried with 9.0-RELEASE and 9.1-RC1.

I search mailing-lists and the web but can't find an answer.

Did I miss something?
