I it not the size of the kernel itself. It depends on how many RAM I
give to the system.
the next dmesg output is the same kernel but with MAXMEM set to
448*1024
Now the isa_dmainit goes through. The problem seems to be somewhere in
the vm. isa_dmainit calls contigmalloc, which scans for a 4k page in
the lower 16M memory range, but can't find any.
The break is somewhere between 448 and 480 M. The physical memory
is 512M.
