Windows 10: BSOD @ random times, DRIVER_IRQL_NOT_LESS_OR_EQUAL, L1C63x64.sys Solved

    BSOD @ random times, DRIVER_IRQL_NOT_LESS_OR_EQUAL, L1C63x64.sys

    It's not always L1C63x64.sys, it has also shown NETIO.SYS but only once. I have not seen consistency in activity during crashes, it's happened idling, downloading, playing a game.

    I've seen errors with this driver linked to the Atheros driver or a VPN (I have both a work and personal that have not had any issues), but as far as I can tell those drivers are up to date. The atheros site is down and all I see are "unofficial" driver sites.

    Hopefully the issue is easy for you all to pinpoint! Any help is much appreciated. System info in profile.

    Hello and welcome to TenForums :)

    Your most recent BSOD indicates that you have Driver Verifier running and it has identified ScpVBus.sys which is usually associated with Scarlet.Crush Productions Scp Virtual Bus Driver. It is dated 2013 so there may be an update.

    Please do not continue to run with Driver Verifier as it puts too much stress on your system.

    Forgot to mention that! Yes I tried Driver Verifier but it BSOD'd with the common IO manager violation, forcing me to run a restore. So it's off now.

    I've uninstalled and reinstalled the SCP driver (it's for a bluetooth to PS4 controller interface). Doesn't appear to have had any updates, and googling doesn't seem to relate to the L1C63x64.sys file that most of the other dumps point too, but I'll keep watch for another failure.

    Happened again

    Updated with new dump from today - same one with the L1C63x64.sys. Happened during a game this time, but it's happened idling as well.

    I've now re-installed network drivers directly from Gigabyte since the Qualcomm network drivers are what I see most often when searching for this file. After the reinstall, the version didn't change (4/1/13). I also flashed my bios to the current version. If anyone sees anything different in the logs that might be an issue, let me know!

    The only additional information I could extract was related to a driver jnprns.sys which is a Juniper Network driver. Are you aware of any updates for this? The current driver is dated 30/10/2014.

    Hm, that's for a work VPN. Looking into it, there was an update to one of its components 2 days before the first crash. I've uninstalled everything for now to test. If it seems stable, I'll reinstall from the newest version of that VPN software and see.

    Latest batch of bsods

    Had another rash of these BSODs at random times - the juniper driver has been uninstalled for a while, so I guess that eliminates that. If these still point to scarlet crush used in DS4Windows, I guess I will try to uninstall it since there aren't any updates.

    Uploaded dump attached. What do you think?

    most recent bsod is from 20.02.:

    0x000000D1:    DRIVER_IRQL_NOT_LESS_OR_EQUAL (20.02.2017 08:22:36) [Windows 10] 
    CAUSED BY:     L1C63x64.sys [16.07.2013] * Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.30) * => Official site:  
                   jnprns.sys [30.10.2014] * Juniper Network Agent driver * => 
    PROCESS:       LCore.exe 
    Usual causes:  Device driver

    As u can see Juniper is running. Please update or roll back those driver:

    L1C63x64.sys [16.07.2013] * Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet * => Official site: Drivers | Qualcomm
    jnprns.sys [30.10.2014] * Juniper Network Agent driver * => Download Software - Support - Juniper Networks
