Linux shows:
   console: mmc0: Problem switching card into high-speed mode!

QEMU MMC support is not in good shape, and high-speed SD card support is 
limited. I keep procrastinating at reviewing your SDHCI patch hmmmmm.

So you added:

  * DMA transfers
  * Direct FIFO I/O
  * Short/Long format command responses

I'd start diffing the trace output of the following events:

allwinner_sdhost*
sdcard*

with both kernels.
