User-space is Fedora 15 x86_64 w/ final updates, plus mplayer-1.0-0.129.20110917svn from rpmfusion. There are no binary-only or otherwise out-of-tree kernel or X drivers anywhere on the machine. Please revert or fix this breakage before kernel 3.7.0 final. /Mikael -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
