  I usually get a kernel panic (page fault, following by disk sync ...
giving up ... reboot) with 512K of cache enabled.  Generally it will
boot the OS OK (but not always) but compiling the kernel will generate
the panic everytime.

  I am sending all the cache back for now.  All the machines have 64M to
128M of 60ns EDO RAM.  Should I bother with the additional 256K of
cache?

  Thanks,

  Tim
