Andrey, Stephen,

We still have problems with this patch in https://bugzilla.kernel.org/show_bug.cgi?id=43278
so some more testing will be necessary, I'm afraid.

I will send a series of ACPI and PCI patches I have collected so far,
that I'd like you to test on top of kernel 3.4.0 with commit
151b61284776 reverted.

Please let me know if suspend/wakeup work for you with these patches applied.

I get the usual freeze on suspending with these patches.

I see.

Please try to unapply [4/4] and see if that helps.

It helps.

Andrey, can you try out Rafael's patches 1-3 (with 151b... reverted)  
and see what happens if the EHCI controllers' power/wakeup sysfs
atributes are first set to "disabled"?

It freezes.

Well, that means trying to work around this through changing the algorithm
of selecting the target state of a device wasn't a good idea after all.

Still, we've found some bugs in the process, so it was worth the effort.

Please attach the output of dmidecode from your machine.

Attached.
