I'm running FreeBSD kernel without ubldr, so u-boot loads kernel and then jumps to kernel starting address. It turns out that kernel starting address, which was always stable, was changed suddently and the result was same like in your case. Thus, maybe it's worth a try to find out how ubldr is run from u-boot and which is its starting address. Svata > I have no further actions I can think of until I get an FDTI cable.
