Hi Guillaume, I tried the same on LS1028A-RDB board with 5.11 kernel and my submitted patch applied. Board booted up successfully: https://pastebin.com/15D91K5k I used OP-TEE from OP-TEE github repo: https://github.com/OP-TEE/optee_os with commit https://github.com/OP-TEE/optee_os/commit/d1447353d3f80ae49053b54f525a0a4cf5e4cde7 Which OP-TEE version you used for CI ?

Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org but this one looks valid. The kernel is hitting this issue: [ 5.326403] kernel BUG at arch/arm64/kernel/traps.c:406! Full log: https://storage.kernelci.org/next/master/next-20210316/arm64/defconfig/gcc-8/lab-kontron/baseline-kontron-kbox-a-230-ls.html The issue can be reproduced with a plain arm64 defconfig, and doesn't seem to be impacting other platforms on kernelci.org. More details can be found here: https://kernelci.org/test/case/id/605057a041fc669ff0addccc/ Please let us know if you need any help debugging the issue on this platform or to try a fix. Best wishes, Guillaume
