I have observed timeouts on a cubietruck. The increase to 40ms is completely arbitrary and Works For Me(tm). I couldn't find a good reference for how long you are supposed to wait, although googling around it seems like tens of ms rather than single digits is more common. I don't think there is any harm in waiting a bit longer. Signed-off-by: Ian Campbell <ijc@hellion.org.uk> --- drivers/block/ahci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
