Decklink Duo 2 CRASHING Windows 11 Pro

I have a new Windows 11 Pro PC, with all of the Windows Updates applied, and no other new hardware or software installed on a “Brand New”, “Just out of the box PC”. When I install a Decklink Duo2 PCI card and load the most current Desktop Video 12.4.2 software, Windows Crashes with Bugcheck Errors. When I “Uninstall” the Desktop Video 12.4.2 software the “Bugcheck Errors Stop”.

Upon Analyzing the Windows Memory.dmp file, the results show:
1. Bug Check error 0x133
2. Unable to load BlackmagicIO.sys
3. Identifying BlackmagicIO.sys having an unknown function (BlackmagicIO!unknown)

The results of WinDbg analysis below, showing just lines containing text “Blackmagic”

I’ve been working with Blackmagic (408) 954-0500 support for over 3 weeks and they are out of suggestions on what to do. I need someone in Blackmagic Developer Support to help fix this problem!

Has Blackmagic certified the Desktop Video 12.4.2 software to work on Windows 11 Pro?

!!!!!HELP!!!!!

Hello Doug,

I just bought new Decklink 8K and I am also experiencing stability issues. I haven't tried to look at the memory dump yet but I have a feeling that the latest Desktop Video 12.4.2 has some issues on Windows 11.

My setup is brand new with ASUS PROART Z790-CREATOR, which should have more than enough PCIe lanes and everything. PC works perfect without Decklink inside it. When I put the card in I start to experience random BSOD, sometimes machine has even trouble booting and goes through 3 blue screens before it launches correctly. From what i observed crashes often happen when application like Skype, Teams, Discord launch. My theory is that these apps check for connected audio/video interfaces and when they touch BMD driver it crashes the whole system. When it does work tho... it works just fine with no issues. I even put the card into much older machine with Win10 and there are no issues what so ever with same 12. 4. 2 driver.

I don't really like wasting whole day and reinstall this new PC to Windows 10 just to test BMD the driver. This is something manufacturer should do. Or at least clearly state if the driver is tested and certified for Windows 11.

I will do more testing and play around with other cards I have, maybe i will try older driver as well. But there is just as much time i have available to play around with this.

Jeff,

I found a consistent triggering event in the Windows Event log that precedes the DeckLink BSOD. By Tuesday I will post the event observations so BM System Developers can weight on fixing the BM Software.

Other people, including myself are having this same issue:
viewtopic.php?f=18&t=175270

So far USA support has been pretty ambivalent about it and hasn't offered any fixes, other than suggesting rolling back the driver - which i did to 12.2.2 and still continued to have the same issue.

It's clearly an issue that needs to be addressed by them.

PROBLEM
Decklink Duo 2 Hardware and Software Crashes Windows 11.

OBSERVATIONS
1 - With Just Decklink Software – No Crash
2 - With Just Decklink PCI Hardware – No Crash
3 - With Both Decklink Software & Hardware – Crash
4 - With Desktop Video V12.4.2 and #3 configuration – Crash
5 - With Desktop Video V12.2.2 and #3 configuration – Crash
6 - Windows Event Log Error from the Memory.DMP file.
Unable to load image \SystemRoot\System32\drivers\BlackmagicIO.sys, Win32 error 0n2 Value: 0x133_ISR_BlackmagicIO!unknown_function
SYMBOL_NAME: BlackmagicIO+51e1f
MODULE_NAME: BlackmagicIO
IMAGE_NAME: BlackmagicIO.sys
FAILURE_BUCKET_ID: 0x133_ISR_BlackmagicIO!unknown_function

TRIGGERING EVENT
1 - Just Prior to the Windows Bugcheck 0x133 Crash, the same Event Error occurs.
2 - Network Adapter - Intel(R) Ethernet Connection (17) I219-LM Network link is “Disconnected” with a Windows Warning for e1dexpress Event ID27
3 - This Error with the Intel(R) Ethernet Driver correlates directly with the Bugcheck 0x133 error associated with BlackmagicIO.sys.

DRIVER UPDATE - Test Observations
Windows installed Intel driver - e1dexpress - Windows Immediate Crash
Alternate Intel Driver - e1i68x64.sys 6/24/21 v12.19.1.32 - Works for 24-36 hours then Windows Crash
Alternate Intel Driver - e1d.sys 1/30/22 V12.19.2.45 - Windows Immediate Crash
Alternate Intel Driver - e1d.sys 11/3/22 V12.19.2.50 – NO Crash - So far working over 36 hours

NEXT STEPS - BM System Developer Support
Assuming the Observations, Triggering Event and Remediation steps to eliminate the Windows Crash associated with Decklink Duo 2 provide valuable insight into the source of the Crash.

What steps can BM System Developers take to monitor for the Ethernet Connection (17) I219-LM Network link Disconnect occurrence and prevent BlackmagicIO.sys from Crashing Windows?

Hey guys, thanks for reporting this - your messages have not gone unnoticed. Please bear with us while we work out what might be going on.

Alternate Intel Driver - e1d.sys 11/3/22 V12.19.2.50 – NO Crash - So far working over 36 hours
Doug F.

Thank you for the valuable details.

Does it still hold up with V12.19.2.50 ?

Shafiro,

Since 30-May-2023, there was one BSOD relating to MMCSS.SYS. However, the Memory.DMP file analysis did not point to BM as the source of the problem in this instance. Other than this one BSOD occurrence, the Windows 11 system has been error free for over 4 days with the Intel e1d.sys 11/3/22 V12.19.2.50 Driver Update installed.

Thank you.

Highly grateful !

I haven't solved the problem in any way. My computer is idle, and I really need it in working condition...

No intel ethernet on a computer I'm testing with (Marvel 3.1.3.0 - 10GB) - and same issue. On other systems, downgrading to Windows 10 has helped to stable running, but Windows 11 and BMD driver has an issue. I thought it might be a Windows 11 22H2 issue, but the latest computer I'm testing with doesn't have it installed.
