Tried your updated ramdisk, still no boot.
No more missing modules, but the mount still fails in the same way.
USB Mass Storage support is now properly loaded. Here is an excerpt from 
the boot screen:

Note that it takes about 5 seconds for mount to fail.
Something wrong with /dev or /sysroot in the ram disk ????

I'll try the next joyride (2205 ?) too.

My firmware is now Q2E11 (got updated during one of these tests when my 
xo-1 was on net power)
