Aargh I though I had that fixed in RC1 :( :( Didn't test -RELEASE on
a G3 :( It's in pmap_bootstrap when doing the cut-over from
OpenFirmware's management of VM to FreeBSD's. I thought it was
instruction cache-alignment related but maybe not.
Would you be able to try RC1 ?

The keyboard doesn't work with the debugger that early in the boot
since it's USB and hasn't been probed yet. I've thought in the past
about modifying syscons so that the PROM could be used until USB is
probed, but it's not pretty. However, it does allow 'boot -d' and
diagnosis for these types of panics.
later,
Peter.
