So what you did is,
# mount -t aufs -o br:/rw1:/ro1:/ro2 none /aufs
# mount -o remount,prepend:/rw0 /aufs
# mount -o remount,mod:/rw1=ro /aufs
and crashed.
Won't you try this patch which produce more detailed debug information
at remount time, and send me the debug log?
You meight need to change these things to receive kernel debug log.
# echo 8 > /proc/sys/kernel/printk
(/etc/syslog.conf)
kern.debug /var/log/debug.log
# restart your_syslog_daemon
serial-console, netconsole or remote-syslog are recommended too.
