This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig5508B17968707230AD2810FF Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello, r284665 causes ahci(4) to fail with timeouts when using MSI (the default)= =2E 'hint.ahci.0.msi=3D0' is one way to make ahci(4) working with r284665, bu= t obviously not the desired solution, it just disables usage of an MSI. I can't find suspicious code in r282213 which could cause this strange regression, but I verified carefully that problem arises with r284665. Actually, r282901 (https://svnweb.freebsd.org/base?view=3Drevision&sortby=3Ddate&revision=3D= 282901) is the real trigger, verified by putting nooptions RACCT nooptions RACCT_DEFAULT_TO_DISABLED nooptions RCTL into my kernel config -> problem vanishes! Setting "kern.racct.enable=3D1" doesn't make any difference, as soon as 'kern.features.racct' exists, there's the ahci(4)/ahcich2 timeout and machine doesn't finish booting. Unfortunately, I don't have any idea how to track this down to the actual culprit, but I hope the RACCT hackers do have ;-) Shall I open a bugzilla ticket? Thanks, -Harry --------------enig5508B17968707230AD2810FF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAlWhWOYACgkQLDqVQ9VXb8gIMgCfQECqAbUSiE2Htldz5KzKCLxA eoIAnR9jtlgIs1XEeuLKXvkaOh9j2HFa =BDMT -----END PGP SIGNATURE----- --------------enig5508B17968707230AD2810FF--
