The constructor of the "Block_device" in the L4Linux block
para-virtualized driver simply waits for the connection to the Block
service. It can't get a connection, because the sd-card driver seems to
exit when trying to detect the card. Have a look at this part of your log:

[init -> sd_card_drv] Could not detect high-capacity card
[init -> sd_card_drv] C++ runtime:
Sd_card::Host_controller::Detection_failed

Maybe, you're not using a high capacity card? The driver only supports
SDHC cards.

Have a look here:

I've written a simplified version of the l4android.run script for you,
which runs on Fiasco.OC/Pandaboard only.
