Kernal didn't resgister IRQ 23 when booting. Hmm....the only '23'
number I can find in kernel is in traps.c.

Why a 23 IRQ was triggered?

The usual reason would be a failure to correctly initialize an interrupt controller, or the Status.IM mask field. The kernel complains precisely *because* IRQ 23 wasn't registered, but an interrupt was nevertheless delivered that was decoded as being that IRQ.
