Public bug reported:
VERSION="13.10, Saucy Salamander"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 13.10"
VERSION_ID="13.10"
vmlinux-3.11.0-5-powerpc-e500mc
When SysRQ is enabled through /proc :
echo 1 > /proc/sys/kernel/sysrq
All responses from SysRQ sequences are redirected to /var/log/syslog , not the
serial console.
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.
