The patch is now back in -next and I'm seeing this issue again on 32 bit arm: https://lava.sirena.org.uk/scheduler/job/2577791#L5864 and arm64 too: https://lava.sirena.org.uk/scheduler/job/2577791#L5864 with bisection pointing to the same commit. --ZJ9xKgCJ7cPdC61k Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmm7CDoACgkQJNaLcl1U h9Cxfwf/TW8W9bDoGCUgHKOF1sT6v+rF/HIAj5ZvvZEwMr8oJ5HQ3NTopeSFkhoH 2bLQkSK6Wap1ElRc8qNB1DUi2ElcC5F30oTZycoA6SPvo8wJEvqX2rkEd1iFmk5G He9AfuBV85Mfay0aazqJ3GBgaEpaPGNoDyJ0UkOlDd78pHO0RIuSbeXrSpqbOZxU cDU/DEWWaA5itUxhQ008MNGhz23JzG6b/zYfpZrl4KymHW2GGvFNDjxQ1CZcvWFn tzi4rBWyEOa2mQExee8wwpqaMPotZJUuhg6Q78hSoUPm8sabPKTskjuZlIRh7NGq 32nriGcc4gM54HnjowK1LQ9hWtpQLA== =j7Gz -----END PGP SIGNATURE----- --ZJ9xKgCJ7cPdC61k--
