Re: mmc0: Too large timeout requested for CMD38!

2011-12-02 Thread Paul Schilling
Hi,

This occurred on two different but large SD cards.

 The 32 GB card that produced the output has the following specs:

· Brand Name: EBS

· Model: 32G_TF_C10_1A_R4ORG.2

· Class 10



The 16 GB card that produced the output has the following specs:

· Brand Name: Samsung

· Model: MICROSDHC 16GB

· Class 2

Thanks,
Paul Schilling

 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
