Nothing landed that I'm aware of. Are you on SDIO, SD or eMMC? Trying to do UHS? I know that this patch mattered for me for UHS: 7c5209c315ea mmc: core: Increase delay for voltage to stabilize from 3.3V to 1.8V Also important for UHS (for at least some folks) were patches like: 9c85f37a2984 mmc: core: Add mmc_regulator_set_vqmmc() ...that attempted to get voltages more proper... In the ChromeOS tree we did just land treating HLE errors as data and cmd errors <https://patchwork.kernel.org/patch/5978711/>. It's not wonderful but it's better than letting an interrupt go off forever... -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
