Recently my Amiga would not boot it would freeze after it loaded asimcdfs.
I have an A4000 and I'm refering to an old IDE CD-Rom drive (Toshiba 4x). I had some problems a time ago: When the CD was in the drive (cold boot), the Amiga wouldn't start (reset, some HD reading, led blink, reset and so on). If I inserted the CD once the WB was loaded, it would just reset the system (with no warning/software failure). I changed the drive and I had no problems since that.
I hope not to be any serious thing (the PPC itself). Try to unplug-disable the CD-drive (a scsi I think).
