well, it turns out it was an hardware issue, and not the one I expected:
I though it would be CPU or cache, but I swapped the motherboard and symptoms
persisted. Now that I remplaced all the RAM, it seems stable again.
I also couldn't get the panic on a SS2 or SS1+.
Sorry for the noise, and thanks for the sparc course !

The IPX has a V7 processor. But the V7 also has this register windows
mechanism, isn't it ?
