Windows 10: DRIVER_IRQL_NOT_LESS_OR_EQUAL - CH341S64.SYS BSOD

Hello,So the last couple of weeks I've been getting bluescreens related to my arduino. They happen at random. I've tried reinstalling the latest drivers and changing usb ports. I also can't think of any program or driver I've installed that could interfere with it.Driver analyzer didn't work as it wouldn't load into windows after restarting. I used windbg to look at the dmp files but don't know what to make of it. The last two dmp files are uploaded to my onedrive.https://1drv.ms/u/s!Aptl88MzzSaVik5jyqGYOl0XJoTf?e=qCsN23I'm using windows 11 version 22H2 and windows says it's up to date.Let me

:)

 

DRIVER_IRQL_NOT_LESS_OR_EQUAL (CH341S64.SYS)

Checked Matlab forums, no mentions of it.

Arduino forums have a few mentions of CH341S64.SYS, but none in relation to bluescreens.

As I mentioned in my original post, there is no dump file because the bluescreens hangs at 100% complete, so Windows doesn't write one.

 

DRIVER_IRQL_NOT_LESS_OR_EQUAL (CH341S64.SYS)

Been having some issues with bluescreens lately. It appears to be related to Arduino drivers and software related to controlling a relay through it. The problem is the bluescreen screen hangs at 100% complete, so there is no dump file to be found. I did
enable DisplayParameters for more info, though I'm at a loss about where to continue looking after that. Appears to happen fairly consistently if I let my program run for a good ~30 minutes and then try to activate the laser through it. I got some advice that
the driver failing is part of the WDM_64 driver for CH341 serial, developed by
www.winchiphead.com. It was a bit hard to find info on this, being Chinese components and all, but most likely, it's the USB driver for the Micro USB ATmega328P Development Board for Arduino UNO R3 I'm using.

Stop code is of course 0xD1 DRIVER_IRQL_NOT_LESS_OR_EQUAL

CH341S64.SYS failed

Parameters:

0xFFFFD906C3F81E39

0x0000000000000002

0x0000000000000000

0xFFFFF8027D9FBF40

Aside from it being a read operation, I don't really know where to start looking here. Anyone have any advice?

 

BSOD - driver_irql_not_less_or_equal (l1c63x64.sys)

Hi Seung,

Sorry for the inconvenience caused by BSOD - driver_irql_not_less_or_equal (l1c63x64.sys).

Please let us know the make/model of your computer.

The L1C63x64.sys is the Atheros LAN driver and I would suggest to uninstall and reinstall the Atheros LAN driver but install the latest Atheros LAN driver by visiting the manufacture's website and avoid using any LAN driver available though Windows Update.

However the problem could also be with any VPN software and other software so make sure you have the latest version of each of these software.

If the errors continue uninstall the VPN software and check if the issue persist.

Hope this helps. Get back to us for further queries for BSOD - driver_irql_not_less_or_equal (l1c63x64.sys). We are happy to help!
