If you want to test if the SD card is used, you can patch your kernel to turn on a LED when the SD clock is active and switch off the LED when it has been inactive for more than 0.3 sec. It is a good way to test.
If you do not like the LED idea, you can use printk(KERN_WARNING, "SD_CLK ON"); whenever the SD clock is activated, and printk(KERN_WARNING, "SD_CLK OFF"); when it is disabled. Maybe also add a timestamp. This way, you will know if the SD card was in use when you tried to get your fix. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
