           Summary: Q45/Eaglelake chipset, S3 suspend resets box
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.28
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Sleep-Wake
        AssignedTo: acpi_power-sleep-wake at kernel-bugs.osdl.org
        ReportedBy: clemens at endorphin.org


On the new Intel Q45 chipset (Eaglelake) a simple
echo -n mem > /sys/power/state
means a system reset when hitting the power button to try to wake up. I assume
that not wakeup fails but going to sleep fails because of the following:

If I disable the PWRB wakeup by echo PWRB > /proc/acpi/wakeup, I still can
"wake up" the box by pressing the button. (wakeup here means to a rebooted
system). So I presume that the box is not in S3 but simply shut down. Otherwise
it should refuse to wake up.

This is on a plain Q45 box, no additional hardware.
