There is no such thing as 64M DIMM for O2. Put correct memory into your machine and
both of these problems will be solved.

I've just been able to start 2.6.11 from my own compilation on IP32.

Can I have some help about following problems/comments ?

1/ It was really difficult because kernel was falling in breakpoint call (BUG macro) in free_bootmem_core. => I've successfully try to comment this BUG macro in free_bootmem_core (bootmem.c) Of course, I'm thinking this is really sad... but I've a really poor knowledge in kernel development...
may someone can explain how to solve such issue in a better way ?
This breakpoint was boring me since 2.6.10...

2/ There's also a problem with ip32-memory.c, which isn't able to detect 64MB dimm. Yet, not enough knowledge for processing bankctl (prom_meminit) in the nice way for detecting 64MB dimms... (All memory slots are used on my O2: slots 1 to 6 with 32MB dimms and slots 7 & 8 with 64MB dimms) .
