I tried the new kernel, and find it still could trigger the cpu_lockup
several times during my 20 reboot cycle, I will upload the log for your

Thanks.

Hi Paolo,
It works after setting the secure boot to disable status, but the dmesg
still could capture the lockup message, about 50% rate of within 7

Please help to review the attached logs for more details.
