MIPS Alchemy machine don't boot *again*
Hi! all,
My Alchemy machine was not able to boot though build the binary of
evbmips-el at current 20100120.
warning: no /dev/console
init path (default /sbin/init):
init: copying out path `/sbin/init' 11
pid 1(init): ABI set to O32 (e_flags=0x1007)

User-level: pid 1.1
Then, I linked init(1) statically and tried booting again. As a result,
the following message was seen in the place where init(1) tried the
execution of sh(1).
init path (default /sbin/init):
init: copying out path `/sbin/init' 11
pid 1(init): ABI set to O32 (e_flags=0x1007)
Shared object "" not found
It try to load the shared library with no name. X-<
sh(1) links the following libraries.
# ldd /bin/sh
/bin/sh:
-lc.12 => /lib/libc.so.12
-ltermcap.0 => /lib/libtermcap.so.0
-ledit.3 => /lib/libedit.so.3
Then, I did the patching attaching diff to ld.elf_so and tried debugging.
However, I saw the strange phenomenon further.
This correction taught to me, sh(1) loads libtermcap, libedit, and no-name
library.

Is my debugging wrong?
Or does anyone understand the cause? (paging? or cache?)
Please give your idea to me.
Thanks,
