mmc0: Too large timeout requested for CMD38!

[Paul Schilling]

I am getting the following error when trying to use a swap file on a
large 32GB SD card formated with EXT4.

Thanks,
Paul Schilling

Any thoughts on this s3c error?

Thanks,

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

Re: mmc0: Too large timeout requested for CMD38!

[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
