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.

Trying to follow the ACPI spec too closely may be a bad idea.  We 
should try to copy what Windows does (whatever that is!).
