Could you disable the CONFIG_MMC_RICOH_MMC and try again?
This setting is only relevant to MMC cards, and I have seen some
problems with it.
Also please post lsmod, dmesg, lspci output.
Did you do a suspend/resume cycle before this test?
You can also contact me via IRC (freenode, oftc, my nick MaximLevitsky),
and I try do some debugging.
Best regards,
