I'm afraid to say that after adding these patches, I find that when Xorg starts, the thing appears to lock up. Bisecting points at: imx-drm: ipu-dc: Wait for DC_FC_1 / DP_SF_END interrupt being the culpret - booting with the patches up to and including: imx-drm: ipu-dmfc: Wait for FIFOs to run empty before disabling works fine. -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
