> This reverts commit d52848620de00cde4a3a5df908e231b8c8868250, which
> was originally put in place to work around a s2idle failure on this
> platform where the NVMe device was inaccessible upon resume.
>
> After extended testing, we found that the firmware's implementation of
> S3 is buggy and intermittently fails to wake up the system. We need
> to revert to s2idle mode.
>
> The NVMe issue has now been solved more precisely in the commit titled
> "PCI: Disable D3cold on Asus B1400 PCI-NVMe bridge"
