OK, I'll have to get my peach-pi or peach-pit up and running again. I ran out of desk space and I haven't gotten it set back up. :( I've been testing on an rk3288-based device. Past experience has taught me that the rk3288 dw_mmc works differently than the exynos one, so perhaps this is a difference. Could you possibly patch in something like and provide the console for the failure? I'll put it on my list to try this myself, too > I was checking on v4.1-rc5, git hash as below: > > 862e58a mmc: dw_mmc: Wait for data transfer after response errors > ba155e2 Linux 4.1-rc5 > 5b13966 > > Not sure if I missed any dependent patch??

I have some old version of the DesignWare TRM, so possibly something is different in the newer one... -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
