Sorry for sending directly. I have some problem for sending with Samsung account. > > > I want to know the situation after removing the BROKEN_R1B quirks. Refer to below patches..already applied. https://patchwork.ozlabs.org/patch/647364/ https://patchwork.ozlabs.org/patch/647365/ Exynos boards what used the sdhci controller were very slow before removing BROKEN_R1B. When i posted the BROKEN_R1B, it was too old..I think this quirk doesn't need anymore. But i can't test other boards what used this quirks. If you can test it..it's helpful to me. >> > > How would I test that? > Basically trying to write 100s of MB to mmc on the rpi3 was failing very > often after applying the "Speed up mmc writes" patch.
