Based on your commit message, it sounds like the platform works theWhen we "quiesce" a machine, some applications may not stop disk I/O promptly,
majority of the time. Is it possible that NVME_QUIRK_NO_DEEPEST_PS is
sufficient for this? Or do you really need to disable it entirely? The
power usage differences can be meaningful.
Also, 30 minutes of idle is an eternity for APST to kick in, so I'm
curious if there's something else going on here or if the breakage
occurs earlier than that.
