Pongrácz, All,

For the record so it gets archived on the list, after our discussion
on IRC:

  - add 'rootwait' to the kernel command line, as USB can be pretty slow
    to enumerate the devices on the bus

Kernel seems to wait forever, so:

  - check that all is built-in: USB driver, USB mass-storage, SCSI
    support, SCSI disk support (maybe a few things else...)
