Description Chester Lin 2023-09-08 08:03:02 UTC 
On some aarch64 CPUs, the grub2 can always experience unexpected system reboot while jumping to the Linux kernel. Based on the patch suggested by ARM [merged in Fedora39]:

https://github.com/rhboot/grub2/commit/4f9d3f4f8d7866c69e52ba7d81562daea38b22e6

The kernel pages are allocated as EFI_LOADER_DATA rather than EFI_LOADER_CODE, which still causes execution failures on some arm64 machines, such as Microsoft Surface Pro X [CPU: Microsoft SQ1 co-developed with Qualcomm] and Lenovo X13s [Qualcomm Snapdragon 8cx gen3].

In order to enable openSUSE on Lenovo X13s and other QCOM-based aarch64 machines in the future, it's necessary to solve this boot issue on arm64.
