__pm_runtime_idle() returns -11!

[Kelly Bowa]

Hi Rafael,

I get the following error messages in dmesg:

[    0.488758] ACPI: Enumerating devices from [\]
[    0.489673] PM: Adding info for acpi:LNXSYSTM:00
[    0.489856] acpi LNXSYSTM:00: __pm_runtime_idle()!

__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..
