[Kernel-packages] [Bug 1282201] Re: SysRQ over serial console redirects to syslog

2014-03-08 Thread Ben Collins
John,

This isn't a bug. You are normally booted in Linux with the quiet flag
passed to the kernel command line. You won't see output like this unless
you either boot without that flag, or run a command such as dmesg
--console-on or twiddle some bits in /proc/sys/kernel/printk.

This is normal behavior.

Title:
  SysRQ over serial console redirects to syslog

Status in “linux-ppc” package in Ubuntu:
  Invalid

Bug description:
  
  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.
