As of next-20150526, the ST u8500 Snowball board has been failing boot
in linux-next, and was bisected down to this patch (commit
ad69674e73a1 in -next).   Full boot failure attached.

I have not dug any deeper, but can confirm that next-20140526 with
this patch reverted boots again on the snowball board.
