This is under Windows, but..... >=20 >=20 Just for the record. Another box, running as a server with CURRENT on-top of a Intel(R) Core(TM)= i3-3220 CPU with Ivy-Bridge HD2500 graphics, crashes/blanks screen when going into grap= hics mode with vt() (having kernel modules drm2 and i915kms already loaded via loader.conf= ). This hardware is now for two years in use and the CPU is much older. The CPU is about to be replaced by a XEON E3-1245 v2 with P4000 iGPU graphi= cs (only). At this moment, I'm highly afraid of having hardware that is not working even = with CURRENT. --Sig_/L6EeeT2OvcSqYkcU30EtBkj Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUJs7BAAoJEOgBcD7A/5N8Oh8H/0tkOFXpYYgWHynVPQh413pX aGlzC8i88Y64AFFlFd/hfLge5hSgmCBabC9FCpRzMqGq6QXgkvbycybB5bchZESr j/VVQqXjGiafGiMuAa5WhQePoaJaTRWPJ+rshhC17MaXFgSPJ9cLzN7h6ed2z5ce adz5ltkLruEXFh1O5L89eI2R+K1O6fUlKtMI9tj+bE755aOi8yNCWfC1wlxY95p0 DuxuIWeUPJgltg66SotPVWbI9p05eqcS0+3HGSPZW5//Rza9OCmy6Zu+YqtIvWXb rFzc0VfnMNCxgyRhLp9TExasgYLWCLrDN7Ij5KLL+AWLkJdM7z5qJ2s7x+Atcww= =ufS0 -----END PGP SIGNATURE----- --Sig_/L6EeeT2OvcSqYkcU30EtBkj--
