[kernel message not available due to kernel panic]

A kernel based on 980408 source crashes immediately after startup with
a panic in "pmap_init":

pmap_init: 081a60000 - 097fe000 (  23429120)
trap type 2, code = 0, v = 0
pid = 0, pc = 0000223C, ps = 2000, sfc = 1, dfc =1

By adding some printf() statements I found out that the kernel crashes
in "pmap.c" at line 499:

        addr = (vm_offset_t) kmem_alloc(kernel_map, s);

Boot a GENERIC kernel.

Sorry, I don't now.
