Anyone have a .config to reproduce this, 'allmodconfig' on > x86 works for me. Actually, I think the current report is for v6.17.1-rc1, so maybe something got missed in a stable backport? My original report was for next-20250728 (July 28). The only response I got was on October 1, but I am pretty sure it was fixed well before then. Also, you probably only get the error when you do a "make modules_install" after the allmodconfig build (at least that is where I got it). --=20 Cheers, Stephen Rothwell --Sig_/ERe9ELmpjLeeLV7K/w=rF49 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmkQNeUACgkQAVBC80lX 0GwmQAf/fM0Bs9Nfx/z6nbUfIRZh8/1JVIQNV2aTeD1nt7G9YH6EjT2jvAQJTEpe B5WbwQG80WyO/PHh+7PjVfH8Y/xHJU0d0dbrtsMszYxTBQYuD9zLpxx09Iiz0MaT bHlI1N0rJ893GJYEeuq5SzwibY8pUcxiCT4H5rsWRq7LNuHDwNzpiNBiHnFh48Ay DoyenNiVlX3JkCFcc+Ah4ea5HRUPVyb06+3eoyXaME66pgpHhJ05TWXiUUi4QzDe ubnkMJp8TyDqD1WIgksONjX3NG56UgxETgjjEkdMJeXwAtpEnXjm5NyHLIk+UmHJ KC5P964Z6NAdSbrylNjVJ2nTTaipUw== =TzBH -----END PGP SIGNATURE----- --Sig_/ERe9ELmpjLeeLV7K/w=rF49--
