Hi Chris.
i didn't know this error is related with s3c.
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?)
Thanks
Best Regards,
Jaehoon Chung
