Ah, that won't have been in there (since the bot is just running off what it finds in git) and indeed looking at the most recent results: https://linux.kernelci.org/test/job/mainline/branch/master/kernel/v5.18-rc2-351-ga2c29ccd94778/plan/baseline/ it does look like it's just Thumb2 that's failing. However that's got Linus' tree as of a2c29ccd9477861b16ddc02c411a6c9665250558 which does feature the above commit so there's something else off (I expect we'll see newer results soon at https://linux.kernelci.org/job/mainline/ since it looks like Linus just tagged -rc3). It does seem to be only this board, other boards are booting the Thumb2 kernel fine, so I'd not be surprised if missing the above commit just confused the bisection. We'd need to rerun a bisection with the above commit in place I guess, I don't have access to trigger that - Guillaume (in CCs) can hopefully help next week. --4N6dQsNEKuGlQVu1 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmJckLYACgkQJNaLcl1U h9D0ZAf/YVWTtOyFNu8dE39ee4I7DLYSzRBwhqbeCk+SD5oT6tEzkJiBx+RIAbFT bCBJj0XwM7vdjzxzU2rjzL3u1myVuCMvDSHLDnXRvk7OjXt0j04jf66wFJfvYsYv IHGUajhd1SoPTJoZk4o4SCGffCV5ORGuB1M/Kg1XnTPQxUoJXPKbsEPif6NkYao+ KIMd2XrVZMwC1GDss6KrgWEOxy5gXjDSaSwrate7ncvYJVZpZVdV/BvPm+Q0PiNQ ZH8h97o1bami3Xuiy9XUr+DqN43RaCS8iJ+ClEURMeL+pNXhpMoZVWWpSOzN+aja eqrLVDQzDcniKQrU3ogZrwrlSZaMeQ== =XpOa -----END PGP SIGNATURE----- --4N6dQsNEKuGlQVu1-- --===============2893086446839053731== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============2893086446839053731==--
