Running 'make oldconfig' I just noticed that PCIEASPM defaults to 
'y' in Kconfig even though the feature is both experimental and the 
help text recommends that if you are unsure you say 'n'.
It seems to me that this really should default to 'n', not 'y' at the 
moment.
The following patch makes that change. Please consider applying.
