WINDBG find Windows 11 getting stuck at "Restarting"

WINDBG

Hi There,

I have a Hyper-V VM of a Windows 11 box getting stuck at "Restarting" anytime it has to Restart or Shutdown, I've tried/done below so far:

  1. I've enabled verbose messages for winlogon.exe during boot/shutdown, the shutdown screen goes through some services/software shutting down and then eventually gets to "Restarting"
  2. Target: bcdedit /debug on
  3. Host: Set-VMFirmware -Vmname VM-HOSTNAME -EnableSecureBoot Off
  4. Host: Set-VMComPort -VMName VM-HOSTNAME 1 \.\pipe\TestPipe
  5. Host: !gflag +sls
  6. Host: !gflag +dwl
  7. Host: !dml_proc

I simply want to be able to see what is causing the hang, the Event Log does not show anything helpful, I want to query a list of the Services and what state they are in to see if it's 1 of those causing the issue but after Googling I can't find or see how to query this from WINDBG?, any help would be appreciated.

Thanks

I had slow restart issues in the past with serial pipe transport. Try switching to NET transport with bcdedit

Does it ever finish restarting or is stuck literally forever? And is this running your code or just a stock VM?

The recommendation to switching to KDNET is a good one...
