[ 0.489862] acpi LNXSYSTM:00: __pm_runtime_idle() returns -11! [ 0.490952] PM: Adding info for acpi:LNXCPU:00 [ 0.491154] acpi LNXCPU:00: __pm_runtime_idle()! [ 0.491161] acpi LNXCPU:00: __pm_runtime_idle() returns -11! .... full dmesg: www.tuxedu.org/kbpm/dmesg2.txt __pm_runtime_idle() returns -11 which could be that it is waiting for other suspend running in parallel or that pm_runtime_cancel() fails to suspend the given device ?.. this causes a noticeable delay in boot time. I get this on 2.6.31-mm1 and ill soon test against 2.6.32-rc1.. -- kbpm
