DPC Watchdog Violation after windows update

[Jendislav]

Hello folks,

I just did windows update on my Windows Server 2016 Hypervisor server and after windows update server is showing BSOD avery 10 or 15 minutes and I am unable to repair it. Server is used as hypervisor for 2 hosts. Before Windows Update there were no problem. Is there any way how to restore server to previous state before update please? Thank you very much.

EDIT:

What I can see now from minidump, all BSODs were caused by ntoskrnl.exe plus some symbol like:

ntoskrnl.exe+15c990, sure I can upload all minidump files somewhere for better understanding of problem.

I got these info from minidumps:

DPC_WATCHDOG_VIOLATION (133)

The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL

or above.
