Help with syslog error messages *ERROR* Unexpected DP dual mode adaptor ID 01 (or 03)

[madmaster]

Hoping to get some assistance or insight into recurring syslog error on my Unraid server.   I've posted about this previously and have received no replies or feedback.  I'm a Linux and Unraid newbie and hope to get some insight or guidance on what may be going on.

 

My system is an Asrock Rack E3C256d4U MB with Xeon E-2276G CPU.  Use it on my home network to store backups and also have a Linuxserverio Plex docker.  The MB has an AST2500 BMC and I have successfully (or so I thought) configured the MB and Plex to enable use of the intel iGPU for hardware transcoding.  Worked great.  Starting with version 6.11.1 and now on 6.11.5 I get the following error messages repeating every few seconds / minutes filling up the syslog file:    

 

 

To load the I915 intel driver, I have nothing in the "go" file and and have Intel_GPU_TOP plugin loaded.  System devices shows both the AST2500 and intel UHD 630 graphics devices recognized and available.  The MB has one onboard VGA output.  I run headless on my home network without a dummy plug.  At some random time after boot; sometimes within a few hours, sometimes much longer; up to 17 days, the error messages start hitting the syslog file.  They repeat every few seconds to every few minutes.  Once they start they do not stop.  I've tried stopping the Plex docker; the error messages keep coming.  I assume it's the i915 driver that is creating the messages.  I don't understand what the message indicates.  I have no DP adaptor attached.  And why do they continually repeat instead of just getting one error message and moving on?   The only way I can get them to temporarily stop is by rebooting the server.  Despite the error messages, the server remains functional.  I can log in and out, use Plex with or without hardware transcoding.  I've searched the web to no avail.  Doesn't seem to be a common problem as I've only seen one other post about the same errors; also unanswered.   To be honest, when I read posts about graphics issues that dive into the inner workings of the kernal and/or the i915 driver module, I'm not able to understand enough to know if what I'm looking at might be my problem or a potential solution.  To date, I've been unable to recognize a pattern of what may be causing the error messages or "force" the error to occur. The error messages just eventually start happening at some seemingly random time after boot.  Any help or insight to get me pointed in the right direction of what I should investigate, including where to post this issue if this is not the correct place would be appreciated.   Attached is my syslog and system diagnostics files if anyone is willing to take a look.                madservr-syslog-20230502-1546.zipmadservr-syslog-20230502-1546.zip

Did you ever solve this? I am getting same error with upgrade to 6.12.2?

[bobokun]

I'm seeing this issue also on the latest version 6.12.3? Have either of you solve this?

i´m getting the rreor to. on Version 6.12.3

[tokamak2077]

I have the Same Error "Unexpected DP dual mode adaptor" after the Updtae 6.12.2 and 6.12.3

[tokamak2077]

I have found the following:

I get the message a few minutes after startup but at the latest when I start my win VM with Intel GVT-g assigned.
Even when the VM is stopped again, the message still appears.
If I now start a SSL connection and run "intel_gpu_top", I get no new messages. even if intel_gpu_top is no longer running.

(iGPU from CPU I8700k)

I installed the following plugin "Intel i915 SR-IOV" and since then the error no longer occurs. Maybe it helps you too. 🙂

Thanks for the tip, the plugin "Intel i915 SR-IOV" fixed it for me too. Which confirms this was a driver issue to start with.

The plugin is labeled as "highly experimental" though... hopefully the new driver will end up making it into the linux kernel.

[tokamak2077]

this SR-IOV plugin is only for newer CPUs as i can see.

12th Gen Intel CPUs and newer
