--- Comment #14 from smithi at nimnet.asn.au ---
I applied these patches (both acpi.c and pci.c) to my then 9.2-R system
(Lenovo X200) on 2014-11-14.  I'd never had Adrian's problem with suspend
but the patches did get rid of 3 apparently harmless error messages, and
add one new one, also apparently harmless.  It's been running fine  since. 

Having updated it to stable/9 a month ago, I assumed these would have been
included, but checking dmesg I confirm they weren't, but are safe for 9.x

This is the new one introduced by the patches (that has now gone)
-pcib0: failed to set ACPI power state D2 on \134_SB_.PCI0: AE_BAD_PARAMETER

And these are the ones the two  patches removed (thus, have returned :)
+pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP0:
AE_BAD_PARAMETER
+pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP2:
AE_BAD_PARAMETER
+pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP3:
AE_BAD_PARAMETER
