Not sure who to CC on this one...

On my new HP 2510p laptop I'm seeing the following error after resume from 
suspend to RAM:

<snip>
CPU1 is up
ACPI: Waking up from system sleep state S3
APIC error on CPU1: 00(40)
ACPI: EC: non-query interrupt received, switching to interrupt mode
</snip>

The weird thing is that this only happens on resume. During system boot I 
can see no APIC related issues.

Full dmesg from system boot plus a single suspend/resume cycle attached, 
and also the kernel config.

I've no idea (yet) whether this is a regression or not.
Note that I've sent a separate mail for the hci_usb related issues that 
are shown later in the dmesg output.

Cheers,
FJP
