I trying to use kernel 3.3.0 on at91sam9g45. But i have problem with detecting uSD card on this kernel.

dmesg:

[ 1.770000] atmel_mci atmel_mci.0: Using dma0chan1 for DMA transfers
[ 1.780000] mmc0: clock 0Hz busmode 1 powermode 0 cs 0 Vdd 0 width 0 timing 0
[ 1.780000] mmc0: frequency set to 0 in disable function, this means the clock is already disabled.
[ 1.780000] mmc_host mmc0: card is not present
[ 1.780000] atmel_mci atmel_mci.0: Atmel MCI controller at 0xfff80000 irq 11, 1 slots


I'm surprised about "mmc0: clock 0Hz busmode".

I've tried kernel 2.6.36, and it works fine. I've tried to use code from it (drivers/mmc/host/atmel-mci.c) in kernel 3.3, but with no success.
