    BSOD:system_exception_thread_not_handled & bad_pool_caller

    Hi all,
    Recently updated win 8 to 8.1 and a week later on, I'm getting BSOD on bootup.
    Initially I got system_exception_thread_not_handled and in automatic repair it rolled back few of the installed updates. But no use.
    Now, sometimes I get system_exception_thread_not_handled and sometimes bad_pool_caller.

    If I first boot in safe mode and then boot normally, then its booting up OK.

    Its driving me nuts. Please help.

    BTW, SF diagnostics generated multiple .dmp files. Is there a s/w to read the dmp file?

    Attached SF.

    Almost all crash dumps seems to blame "Realtek Card Reader" driver as the reason behind the crashes.

    BugCheck C2, {7, 1205, d5fe5, ffffe00004138780}
    *** WARNING: Unable to verify timestamp for RtsP2Stor.sys
    *** ERROR: Module load completed but symbols could not be loaded for RtsP2Stor.sys
    fffff80197129340: Unable to get special pool info
    fffff80197129340: Unable to get special pool info
    GetUlongFromAddress: unable to read from fffff801971c4208
    Probably caused by : RtsP2Stor.sys ( RtsP2Stor+35dd3 )
    Driver Reference Table - RtsP2Stor.sys

    Please follow the below steps.

    1. Update card reader driver.

    Uninstall the currently installed "Realtek Card Reader" driver from "Control Panel --> Programs" completely and reboot the system. Now download and install PCIE RTL8402/RTL8411 card reader driver for XP/Win7/Win8/Win8.1 from the below link.


    2. Update system BIOS.

    Lenovo recommends updating BIOS to the latest version to improve Windows 8.1 compatibility. Download and run the BIOS update utility to do that.

    BIOS Update :

    Report how the system works now. If the issue continues, upload the latest crash dumps.

    Anshad, Thanks a ton.
    After uninstalling PCIe card reader the boot time BSOD is gone for two days now.

    However I'm now facing different issue.
    Most likely the wlan is dependent on PCIe card reader and my wifi gone kaput after uninstall of PCIe card.
    The driver you suggested - PCIE RTL8402/RTL8411 - is not proper I guess coz after installing it, still the PCIe card reader was undetected. I just checked my type and realized it should be RTS and not RTL. So I downloaded and installed PCIE RTS5229 card reader driver for XP/Win7/Win8/Win8.1. Now the card reader is detected ok. But I'm back to the boot BSOD.
    As of now I have just disabled the PCIe card reader driver for booting and my wlan is still non-function.
    I guess RealTek need to come up with fix for this issue.

    Anyways thanks a lot for your help.

    PS: BTW, the dmp files created by SF tool, how can we read it? Is there a software / tool for it? Can you please tell the location where I can download the same.

    To read the crash dumps we need "Windows Debugger" or "Windbg". Explaining how to read crash dumps are out of the scope of this thread but i will post some links which will b very helpful to beginners.

    Since the BSOD returned after updating the driver, please rerun the diagnostic tool and post the zip with next reply. I hope we can sort it out.

    Anshad, thanks for pointing out the "how to debug" thread.
    I set up the debugger and could load the dmp file.
    The latest driver for realtek pcie card reader too has same issue:
    BugCheck C2, {7, 1205, d5f7e, ffffe00003f74a90}
    *** WARNING: Unable to verify timestamp for RtsP2Stor.sys
    *** ERROR: Module load completed but symbols could not be loaded for RtsP2Stor.sys

    GetUlongFromAddress: unable to read from fffff803357c3208
    Probably caused by : RtsP2Stor.sys ( RtsP2Stor+37fa8 )
    I sent mail to RealTek support.
    Is it possible that some other issue is preempting the card reader driver to screw up?

    Is it possible that some other issue is preempting the card reader driver to screw up?
    Yes, it is possible. May be some other rogue driver which is sharing some system resources could be corrupting the card reader driver and forcing it to crash. In that case, we should update all the outdated drivers as a test. Please upload the latest crash dump and i will post the list of outdated drivers to update.

    OK - here is the latest SF zip.
    All the dumps point to only one: RealTek card reader RtsP2Stor.sys.
    There is one dump on WLAN driver - but thats not during boot up. It happened in-between things and is one-off occurrence I guess.

    Realtek card reader and wireless adapter drivers seems to be up to dated. So let us try updating the remaining drivers.

    Realtek LAN : Realtek

    Microsoft Mouse driver : Software Downloads | Microsoft Hardware

    Current version seems to be pre-Win8 so may cause compatibility issues.

    NuidFltr.sys                Sat Apr  9 04:28:16 2011 (4D9F9308)
    Microsoft Intellipoint mouse driver

    If the BSOD continues, please enable "Driver Verifier" by following instructions from the below link.

    Driver Verifier - BSOD related - Sysnative Forums

    This will stress the drivers and force BSOD when a violation is found. After you got two or three crashes, rerun the tool and upload the new dumps.
