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.  If it doesn't,
please try to enable the problematic USB controller to wake up
(e.g. by writing "enabled" to its /sys/power/.../wakeup file before the
suspend) and see if that helps.

Thanks,
Rafael
