Well, I don't know any of the versions you've listed well.  But the
message looks identical to past versions'; in those versions, it meant
that the CPU found itself interrupted, at priority 23, on vector 0x60,
but the OS was not expecting any such interrupt and thus had no idea
what to do with it.

Interrupt level 23, 0x17, is the highest of the hardware-interrupt
levels.  I don't know the 3100 architecture well enough to know whether
it can normally be generated by hardware or not.  The VARM says that
SCB vectors 0x50-0x60 are "reserved for bus or memory error"; it seems
at least moderately likely to me that this is a RAM error.
