This will never work. I bet it didn't work with your old kernel
either. 0x10000 is just 64 kB - this is _never_ enough for an
uncompressed Linux kernel. You will overwrite your kernel while
uncompressing it, which crashes the system. Use a higher load address, somthing like 0x200000.
In the PPCBoot guide(FAQ section),it mentioned
2 possible causes,wrong bdinfo and clocks_in_mhz
I do check it and feel nothing wrong,however
nothing yet.
You have to _unset_ clocks_in_mhz for a 2.4.20-pre2 kernel.
I have a BDI2000,but I think I should debug the bootm
part of ppcboot,however someone says it is quite
difficult to do so( at least for me).
Well, it's not _that_ difficult. Try it out, so you get used to is ;-)
so I am seeking errors in blind.
Just open your eyes, and thou shalt see :-)

Always leave room to add an explanation if it doesn't work out.

Sorry! I lost a zero here,I mean 0x100000,so old kernel can boot there.

I wish it is not that hard,however I can not debug the kernel or
ppcboot according the brief introduction in BDI manual.:(
I want to watch r3,r4,r5,r6,r7 register when ppcboot transferring
to kernel.Could you tell me how to get that? thanks a lot!
