Hi Torfinn,

  Was this with a boot by holding down the 'C' key at power up ?

  If so, it might be possible to try a manual load. Break into Open 
Firmware and

0 > boot cd:,\boot\loader cd:0

  The problem you see has been intermittently happening in releases for 
a long time now. I've never worked out exactly what's going on.

later,

Peter.
