Lenovo Yoga 7 Gen 7: DPC Watchdog Violation (Bugcheck code: 0x133)

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...

    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.
