Can you show me CPU identification lines from dmesg for a verbose boot ? I suspect that you can take /lib/libc.so.7 from 12.0 RELEASE and restore the system. If it helps, please move your existing libc.so.7 into some directory, reproduce the problem with 'LD_LIBRARY_PATH=<path to dir with bad libc.so.7> /bin/ls' and load the core into gdb. I want to see the backtrace for start.
