Created attachment 305130 [details] Kernel log On my VivoBook laptop, I encountered a critical kernel error that caused a system crash. This error occurred while the system was running the 6.2.0-33-generic and 6.2.0-32-generic versions of the Ubuntu kernel, 6.2.0-32 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.

Can you reproduce this issue on latest mainline (currently v6.6-rc2)?
(In reply to Bagas Sanjaya from comment #1) Are these packages good for testing? https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.6-rc2/amd64/
(In reply to Francesco from comment #2) > (In reply to Bagas Sanjaya from comment #1) > > Are these packages good for testing? > https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.6-rc2/amd64/ You should try compiling your own kernel instead. See Documentation/admin-guide/quickly-build-trimmed-linux.rst in the kernel sources for how to do that.
I installed and booted linux-image-6.6.0-rc3_6.6.0-rc3-7_amd64.deb, it works.
