Now I set _SECTION_SIZE_BITS 22 and see what happens next.
I found that readmem for "page table" failed while excuting
init_unwind_tables() in unwind_arm.c and crash exited.
crash: invalid kernel virtual address: f67f000 type: "page table"
Instead of investigating this issue, I continue by skipping init_unwind_tables for a
while.
Because crash gives me a prompt now and I am quite interested in whether it gives me some
useful information or not.
Please check your platforms
arch/arm/mach-<yourmach>/include/mach/memory.h and set both
_SECTION_SIZE_BITS and _MAX_PHYSMEM_BITS to be the same as defined in
the header. If crash works with the correct values, we just need to
find out some way of guessing these.
