I am using a 2.6.35+, not a 3.0 kernel. So with the patch in my board, it
works. Andrei Warkentin has mentioned that, if the mounted device contains root
file system, that patch cannot fix this problem really since the device node
will be changed after resuming back. That is also the reason not

Hi Dong,

Hi Viresh,
I also meet the hang issue when suspending a system with a mounted SD card.
Actually it caused by a dead lock of mmc_claim_host. Maybe we faced the same
issue.
So may be the two mails in the attachment can help you.
Thanks

This patch is removed the DEVICE_DEAD flag for sdhci-s3c.
I didn't know why this flag is assigned.
If this flag is set When card is removed,
ENSDCLK bit in CLOCK control register is always set in sdhci_set_ios().
Because if device dead, be skipped set_ios.

This patch adds support for sdio UHS cards per the version 3.0
spec.
UHS mode is only enabled for version 3.0 cards when both the
host and the controller support UHS modes.
1.8v signaling support is removed if both the card and the
host do not support UHS. This is done to maintain
compatibility

Host is claimed as long as there are requests in the block queue
and all request are completed successfully. If an error occur release
the host in case someone else needs to claim it, for instance if the card
is removed during a transfer.
