VmmemCmFirstBoot freezes Framework Laptop

[Isotop7]

Windows Version

24H2 (26100.2894)

WSL Version

2.3.26.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.167.4-1

Distro Version

Debian Bookworm

Other Software

No response

Repro Steps

• Upgrade to the latest Windows 11 release and wsl version
• Install any distro
• Reboot and login and wait for the deadlock

Expected Behavior

After logging in, I would like to use Windows and also the WSL.

Actual Behavior

After logging in, several VmMem processes are forked, which consume a high cpu load. The process VmmemCmFirstBoot ultimately freezes the PC. No mouse or keyboard input are possible and I have to force reboot the system by holding down the power key.

When disabling WSL or Virtualization settings in the BIOS, the system starts without any problems.

The script asked me to reproduce the issue, which I cannot do because I would have to enable WSL, which freezes my machine.

The log file doesn't contain any WSL traces. Please make sure that you reproduced the issue while the log collection was running.

Diagnostic information

.wslconfig found
Detected appx version: 2.3.26.0
Found no WSL traces in the logs

The bot is able to extract and parse zip files but not read my comment.

I‘m unable to reproduce the issue because I would need to enable VMX in EFI which would start the process VmmemCmFirstBoot after logging in. This freezes my machine INCLUDING the trace script. If you tell me how to disable that process I can generate a trace.

I'm not sure what vmmmemCmFirstBoot is, but it's unrelated to WSL. I would suggest filing an issue via Feedback Hub so this can get routed to the right team, feedback hub will also collect the relevant tracing information.
