Lenovo Yoga 7 Gen 7 14ARB7 82QF: DPC Watchdog Violation (Bugcheck code: 0x133). WORKAROUND: Disabling AMD-V in UEFI/BIOS stops blue screens of death.

LiveKernelReports.zip
Today there's a new BSOD but no dump file as i set it to restart automatically after crash.
This issue is probably able to be fixed by Lenovo as ASUS have a 2 in 1 laptop using the exact spec as mine but no one complain about this issue.

Try to update the mediatek MT7921 = RZ616 Wi-Fi 6E 160MHz from device manager.
The microsoft update catalog shows a new version 24.40.2.575 (25 October 2024) with its hardware id: ven_14c3&dev_0616&subsys_e0c617aa.
FWIW the dumps on 10th Jan and 13th Jan were both likely caused by that wireless card driver mtkwl6ex.sys. However, I can also see that the driver has been updated in between the two BSODs on 10th and 13th. The driver version in the 13th Jan dump is the Oct 2024 version...
Code:
11: kd> lmvm mtkwl6ex
Browse full module list
start             end                 module name
fffff805`1ea70000 fffff805`1ec21000   mtkwl6ex T (no symbols)

    Information from resource tables:
The 10th Jan dump contains the Dec 2022 version of this driver. That makes it unlikely that the driver itself is at fault. It could be the wireless card itself of course, but I don't recall ever seeing this driver referenced in earlier dumps.
 
Update:

Calling Lenovo Support and sending them a lengthy email. They request me to send my laptop, which I am unable to do so until June 2025 unless I manage to find an extra laptop. (16 Jan 2025)

I reported to AMD Global Customer Care, and I sent a bug report as stated in their reply.(17 Jan 2025)

* I stopped uploading complete memory dumps to my google drive when a BSOD occurs to save storage.

First time facing this issue after disabling Virtualization, as reported English Community-Lenovo Community
Just that I have more drivers having that error.
I notice this only when I can't use both my touchpad and touchscreen.

There are also times where the symptom of BSOD gonna occurs show , but no BSOD occurs (it happens last time during that two weeks of testing with virtualization off too if im not mistaken). eg, touch gesture freezes for several second before continue normally.

Did amd want to see the dumps?
They didn't contact me after I sent the bug report.
The content of the bug report is the same as what I sent to lenovo so I guess it should suffice.

I asked a person who happens to have 14ARB7 and 14ARH7 (and facing the same issue for both laptop :oops:), he already sent those bug report to amd (using the amd bug report tool) for two years already.
If you are interested I can ask him to come here too.

On 28 Jan 2025, a very interesting but rare thing occurs again, but this time it can be found in Reliability Monitor.
My laptop freeze, and while I am waiting for it to write the complete memory dump (2 mins freeze I think), suddenly the laptop came alive again normally but using for a several second it freezes again. I waited for 10 mins as usual and hard restart it. There is only one complete memory dump and minidump though.

Sorry but I forgot to run the Sysnative app during that time and already deleted the complete memory dump.

1738422073497.webpZip 1 contains the files for this.
1738422082398.webpZip 2 contains the files for this.

You have already installed the latest versions.
Msinfo shows their start mode is manual... I don't know what effect changing the start mode to automatic would have (it probably only has the effect of making it boot with windows), but you could try it:
Code:
sc config amdi2c start=auto
sc config amdgpio2 start=auto

If after that it still doesn't work, I would also disable amd ryzen master driver afterwards:
Code:
sc config amdryzenmasterdriverv28 start=disabled
sc config amdryzenmasterdriverv27 start=disabled

Did you use the (adreanlin or standalone) amd bug report tool like suggested by Santosh (AMD Global Customer Care)?


I already restarted and things went back normal. Then I ran the first two commands. View attachment 115862

The commands were wrong (i used qc instead of config, I edited the previous post). o_O


Am I supposed to run the last two commands when it fails again?

Yes, only if the problem occurs again.

Yes, it is installed with AMD Software. In fact I did report before too but I never send a detailed version like what I sent to Lenovo.1738430979146.webp

1738431105501.webpBtw I don't remember I have AMD Ryzen Master Driver installed.
