Log: OLPC XO-1.75 A2 A3 - Remove delay on access to external SD now that discharge switches are in place. " t( dir ext:\ )t " shows 562ms before this patch, and 94ms after this patch. Even more time is saved when a directory is accessed. Has no effect on internal SD. #10512.
Breaks A1 external SD for some cards, but we are no longer building for A1 and a workaround can be used prior to access: " dev /sd d# 250 to power-off-time "
