Subject: Re: Commit 4257f7e0 ("PCI/ASPM: Save/restore L1SS Capability for
 suspend/resume") causing hibernate resume failures

Ideally Bjorn's patch should have worked.
Could you please collect 'sudo lspci -vv' (please don't forget to give 
sudo) with Bjorn's patch before and after hibernate?
Also, is it right to say that with policy set to "performance" there is 
no issue during hibernate/resume?
