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
