If your system has already been updated to Windows 11 24H2 and is unstable, there is a temporary workaround that may help until the firmware is updated. The procedure involves the use of Registry Editor Windows to adjust the HMB allocation. To do this:

1. Open the menu Starttype Regedit and right click on the corresponding result.
2. Choose “Run as administrator”.
3. Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorPort.
4. Create new value DWORD called HmbAllocationPolicyif it does not already exist.
5. Double click on the value and set it to 2.
6. Save the changes and restart the system.

This change should keep the system stable until the new firmware is installed. In some cases, setting the value to 0completely disabling HMB also temporarily solves the problem.
