We should at least be logging problems at debug level so there's something for people to go on without having to hack the kernel source. --kVXhAStRUZ/+rrGn Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl7zVEwACgkQJNaLcl1U h9Adowf/bt19xA4Q3/G5xTijEYnOc63YWxQGFynpEFvnpuQuTYuDRwL2ybQHpXkD 7dZqUsmE//n9XDWNSi6IHolSzWRtBVqD+LpF/gmGHcqGsPCstcSLeQMVM5b4l5KV x59+x9cTfoYkQ2XoBNZmmWZwGBYqVJvhW+4TysUX+9JCZgxKOG1LXLuMlL7r9qP2 5nI549k1sjQdiC8pevFkysGucfiOGoKIQfcpMqqlIzCFkBCt5pRTYNQ0e4jUh3gT 8qVPKlbm99aJ5+TGjPWtUzndU9VM08psKQNnguznxAbaHhF+ZA11l1AiIPv2qHkn YtM+Bz+sHfeDkTCKefTLds0G3+8Mmg== =oY2K -----END PGP SIGNATURE----- --kVXhAStRUZ/+rrGn-- --===============1321484039== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel --===============1321484039==--
