Bug Description
On my VivoBook laptop, I encountered a critical kernel error that caused a system crash.
This error occurred while the system was running the 6.2.0-32-generic until 6.2.0-34-generic versions of the Ubuntu kernel, 6.2.0-31 works fine. The hardware used is an ASUS VivoBook K3502ZA with BIOS version K3502ZA.307, last updated on 09/08/2022.
Detaching all USB devices does not fix the issue.
Steps to Reproduce:
Boot the VivoBook laptop.
Start kernel
Expected Behavior:
The system should operate without encountering kernel NULL pointer dereference errors and subsequent crashes.
Actual Behavior:
The system crashes with the mentioned kernel error.
Please let me know if you need further information or logs to investigate and resolve this bug.
