Hi HAI-TAO,
The kernel I use is Linux version 2.4.0-test2 .
I enabled Sandpoint_debug. Here is the __most farther__ the boot goes:
-----
DINK32_ARTHUR >>go 900000
loaded at: 00900000 00914E20

zimage at: 0090B000 00989621
avail ram: 00400000 00800000
Linux/PPC load: root=nfs
Uncompressing Linux...done.

Observed problems:
1) The boot is no consistent.
Sometime it hangs at

It hangs there after entering free_area_init().
I can't find the rountine under /arch/ppc/. So it must be an arch
independent
rountine.
Is it defined in mm/page_alloc.c:void __init free_area_init(unsigned long
*zones_size) ?

The boot goes fine with PPMC7400 on Sandpoint.
Thanks,
