Nodes not booting

[poVoq]

its strange it doesnt show up... what does your DMESG say about mmc2? can you post your dmesg?

Ah, dmsg does indeed give an error:

[    2.486688] sunxi-mmc 1c11000.mmc: data error, sending stop command
[    2.487483] sunxi-mmc 1c11000.mmc: send stop command failed
[    2.487518] mmc2: switch to bus width 8 failed
[    2.487854] mmc2: unexpected status 0x400800 after switch
[    2.494397] mmc2: power class selection to bus width 4 ddr 4 failed
[    2.521669] mmc2: error -110 whilst initialising MMC card

Any idea what this could mean?
