Amiga 4000T boot problem

[X-ray]

Does this business with the software failure happen even if you don't have the hard disk connected? If you take all the IDE stuff out, does this happen?
Has it been playing up from day one that you had it? If not, what was the last thing you did to change the config before the error started happening?

@ Markus

When the battery on my A4KT went flat, I got no software failure. IIRC I ran the machine without the battery for a few days while looking for a replacement, and I got no software failure. I doubt this is a battery problem.

@ Orange

If it is an A4000T he'll have the latest ROMs.

@ HammerD

I was going to suggest that it is a long spinup time on your drive, but if you've tried 3 drives, then I don't know. (unless they are all old drives)
Do you have any SCSI drives that you can test?

Edit: did this crash start happening from day one that you had the machine?

@ Thread

Do all A4000Ts do this, or only some? I haven't had this problem, not even with a CF card.
Edit: that was a stupid question, 'cos they can't all do it if mine doesn't, innit?
Rephrase: how many other A4000T users have this problem?
