From: http://jcapik.fedorapeople.org/files/ARM/kernel-tests/kernel-omap-3.6.0-0.rc4.git0.1.fc18.armv7hl-panda+xfce.txt

[    3.577362] omap_hsmmc omap_hsmmc.0: unable to obtain RX DMA engine
channel 62
[    3.585540] omap_hsmmc omap_hsmmc.4: unable to obtain RX DMA engine
channel 60

First Enable:
CONFIG_DMADEVICES=y
then:
CONFIG_DMA_OMAP=y

The mmc driver was converted to a new dma engine (which also happens
to be new in v3.6-rc) in v3.6-rc but it looks as though the KConfig
depends wasn't updated... Ran into this last week with the Beagle..
