Bug#508599: linux-image-2.6.26-1-686: Increase power_up delay to fix TI readers



Package: linux-image-2.6.26-1-686
Version: 2.6.26-11
Severity: normal
Tags: patch

Hello Kernel maintainers,

To get a SD cardreader working I needed to do

diff --git a/drivers/mmc/core/core.c b/drivers/mmc/core/core.c
index 01ced4c..11f050c 100644
--- a/drivers/mmc/core/core.c
+++ b/drivers/mmc/core/core.c
@@ -492,7 +492,7 @@ static void mmc_power_up(struct mmc_host *host)
 	 * This delay must be at least 74 clock sizes, or 1 ms, or the
 	 * time required to reach a stable voltage.
 	 */
-	mmc_delay(2);
+	mmc_delay(10);
 }
 
 static void mmc_power_off(struct mmc_host *host)


I got that fix from Mandriva
