This patch from NVIDIA fixes the forced-replication method of inducing the timeout and appears to likewise fix the intermittent occurrence of it. The patch will be heading upstream in short order, per the author. Affects only the Tegra mmc driver. -Kamal Acked-by: Colin Ian King --- anrao (1): UBUNTU: SAUCE: mmc: host: Add required callbacks to set/clear CQE_EN bit drivers/mmc/host/sdhci-tegra.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+)
