I know it's not a "bug" per say .

For instance: SySRQ ( break ) l Is suppose to report CPU stack traces . The summary is sent to v/var/log/syslog , not the serial port, which defeats the entire purpose of SysRQ feature which is intended for diagnostics of server issues. The logging behavior can redirected to the console by using : dmesg --console-on This should be the default behavior for ppc ; It is also how x86 has worked in the past.
