I think I'm seeing the same thing on my Centris 660av, 36MB RAM... my
previous kernel, from June 19 sources works fine, but my July 4 kernel
crashes with:

nubus0 at mainbus0
trap type 1, code = 0, v= 10ccd0
kernel: Address error trap
pid = 0, pc = 000A33B6, ps = 2000, sfc = 0001, dfc = 0001

[ register and stack dump ]

panic: Address error

No idea what the cause of the problem is though...
