T15p crash after Hyper-V activation

2020-10-15, 9:23 AM

On My new T15p gen1 i7 after Hyper-V activation Windows 10 2004 crash at first reboot and then crash and reboot Continuously.

if roll back to last restore point, without hyper-v Windows work correctly.

I tried to upgrade from PRO to Enterprise (MPN) but the problem persists.

If I try to restore windows from the original image everything freezes.

Without hyper-v, no problem everything works for hours both in battery and live.

I installed both the latest windows updates and the latest drivers found on the Lenovo site, without any benefit.

OS:

Widows 10 2004 build 19041.572

The blue screen present TbtBusDrv.sys or USBxhci.sys driver failed.

Can someone help me? I took this pc to be able to use even hyper-v without I can also return it.

thank you for any support

Paul

If you search there are some reports that with recent updates with hyper-v some thinkpads are giving BSOD. 

I am also facing BSOD but without hyper-v enabled (though I run ubuntu VM). For me the BSOD are not predictable. They happen immediately or after long time (5/6 hours).
