This issue appears on 6.6.76 onward and 6.12.13 onward, as reported in the stable review [1]. However, the test case passes successfully on stable 6.13. The selftests: arm64: check_hugetlb_options test was introduced following the recent upgrade of kselftest test sources to the stable 6.13 branch. As you are aware, LKFT runs the latest kselftest sources (from stable 6.13.x) on 6.12.x, 6.6.x, and older kernels for validation purposes. >From Anders' bisection results, we identified that the missing patch on 6.12 is likely causing this regression: First fixed commit: [25c17c4b55def92a01e3eecc9c775a6ee25ca20f] hugetlb: arm64: add MTE support Could you confirm whether this patch is eligible for backporting to 6.12 and 6.6 kernels? If backporting is not an option, we will need to skip running this test case on older kernels. > > 1) > Regression on qemu-arm64 and FVP noticed this kernel warning running > selftests: arm64:
