We're seeing issues in all configs on meson-gxl-s905x-libretech-cc today, not just with the kselftest fragment. The initial failuire seems to be: [ 17.337253] WARNING: CPU: 3 PID: 123 at drivers/gpu/drm/drm_bridge.c:1257 drm_bridge_hpd_enable+0x8c/0x94 [drm] full log at: https://storage.kernelci.org/next/master/next-20230111/arm64/defconfig/gcc-10/lab-broonie/baseline-meson-gxl-s905x-libretech-cc.txt and links to other logs at: https://linux.kernelci.org/test/job/next/branch/master/kernel/next-20230111/plan/baseline/ Today's -next does have that fix in it so it's not fixing whatever the original issue was, I suspect it might even be exposing other issues. We are however still seeing the stack filling up, even with a GCC 10 defconfig build. --OZN5I8D63BKoaTA7 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmO+q4kACgkQJNaLcl1U h9Dk9ggAgiyNXp8FESi8ST8bCJzfxxMvylBdG+Z+1Q2//2usTBZ89jQ94M9CVgZr AHSsut/qzDLYBEQQ9VnLXutGV1MEWqwl+K0vILqKKTV2+uwAcbpWOENJwnbGzN7+ fz8MtV05xlt9M1K7qtQnRb01xgt7zXr0lY1HVOpQyJzInoCypdlp9laV/nsQDYh+ X5WPh12TqUbzc1LBqHBV1xpOZ8C+NNptsRuyLM3IJex6Am6xcNTnH4OcEL1vAuWp ASrh9a7w1rxfYBYVUMJIhdCNHZZmaj+NuB2hAEJNnQ7NNGPeaCYMvpe8S5DE4/Uz owLmp0WY+mpnbwzg6IPpQHjNeFiqJA== =gr7z -----END PGP SIGNATURE----- --OZN5I8D63BKoaTA7--
