    DRIVER_POWER_STATE_FAILURE 9f at hibernation with RAMdisk

    Constant DRIVER_POWER_STATE_FAILURE 9f at hibernation while using pagefile on RAMdisk

    Windows 8.1 Pro (32-bit)
    RAM = 10 GB

    When the DRIVER_POWER_STATE_FAILURE 9f on hibernation started, I wasn’t sure about the culprit, because I had made several changes on my computer. One was using Primo RAMdisk to create a RAMdisk in the “invisible” memory (that above the 3.5 GB Windows can see). I also wanted to put pagefile.sys on the RAMdisk, since it is the only way to speed up (actually to reasonable) this computer's behavior.

    When Primo RAMdisk trial period was over, the “DRIVER_POWER_STATE_FAILURE 9f on hibernation” BSODs stopped.

    I got a trial extension of Primo RAMdisk for the purpose of testing. With the RAMdisk created, but no pagefile on that one, the systems goes into hibernation in about 40 seconds – and there is no error. When I allocate some amount of RAMdisk for the pagefile, it takes the system about 6 minutes to try to go into hibernation and then it shuts down “unexpectedly” – practically I don’t actually see a BSOD since the monitor is not active.

    Apart from this hibernation annoyance, when the pagefile is on RAMdisk, I get occasionally “infuriating” BSODs of KERNEL_DATA_INPAGE_ERROR 7a and DRIVER_IRQL_NOT_LESS_OR_EQUAL 0a. These come unexpectedly and I can really lose my recent work.

    What repair do I have? another one apart from “don’t put any pagefile on the RAMdisk”. Is there maybe any conflict with another driver (nVidia?)? Is there any way I can keep pagefile on the RAMdisk?

    While I might give up hibernation (it's springtime anyway!), I am more worried about the other 2 BSODs that may destroy my recent work.

    Note: my pagefile allocation is a little strange. It is spread across 3 drives: some on HDD 1, some on HDD 2 and some on the RAMdrive.

    Software is in very poor condition overall.

    Ramdrive is an issue.


    Update or uninstall:

    pagefile.sys and hibernation?

    I have been testing various things.

    Regarding your reply:

    1. I have no idea how to update or uninstall vstor2-mntapi10-shared.sys. It is a part of VMware software, of which I have the latest version.

    2. Deleted pqntdrv.sys

    kx.sys has no new version and is vital for my audio card.

    4. HECI.sys. There is no newer driver for mobo DG33FB from Intel. They stopped support for this.

    5. Uninstalled afc.sys.

    6. Deleted lowerfilters and upperfilters, although there was no apparent problem with the DVD drive.

    In the end there was no effect. The problem is that hibernation does work with pagefile.sys, If that is corrupted - as part of it disappears when the RAMdisk is disconnected
    (the same happens with DataRAM) - hibernation cannot recover. The same happens if you shut down the system, as the system shutdown in Win 8 uses (by default) Fast Startup, which is a sort of hibernation. The solution is to cancel fast Startup and give up hibernation. At least, until those RAMdisk creators find a solution to preserve pagefile.sys. A RAMdisk seems to be a must, since the accessible RAM of the 32-bit systems (3.5 GB) is filled quickly and a pagefile.sys of about 4 GB is hard (and wearing off) to handle on the HDD.

    You didn't listen so of course. It's like pointing out the obvious as Sherlock. And #4 has 2013 or 2014 driver. Please don't inform me of any issues unless you adhered to advice completely and fully, first. That's why it's there to begin with.

    Not true. Please don't misinform

    Intel® Chipset Device Software for HECI

    The latest driver for DG33FB is 2008.

    Not informing you alone, but anyone who might have the same issue.

    Yes, true. Just listen and install 2013 or 2014.

    And where did you find that?
    A link would have been so easy to post.
