When swapon is performing, i know the card is run the discard. (mm/swapfile.c about line 2050? run discard_swap()) At that time, This SD card's erase_time_out should be too big,so this message may be produced. If i can get the more information, very helpful to me for debugging whether this problem is s3c or not. (What is SD-card's vendor?)
