AFAIK, the 420 and 620 use the same chipsets (my verbose boot looks similar to yours). My kernel is different (simpler), however. I do not know if this could be the cause of the problem, but I have never had to disable SMP on my machine. Only strange things that have happened to me is removing `device ATA' from kernel causes an immediate panic (machine is all SCSI).
