Description Dan Jacobson 2014-09-06 11:02:53 UTC 
All kinds of stack traces upon kernel panic shove vital information off
the screen, for which the average user without e.g., an extra terminal
has no remedy. Furthermore many users have little use for such traces,
and would instead rather see what other messages were output before the
trace and hopefully fit into those vital 24 lines on their screen.

I propose a boot parameter e.g., trace=off that could be used to avoid
having such traces printed.

The idea was reviewed and found easy to implement:

Please also make sure it applies to
Error “fixing recursive fault but reboot is needed”too.

Due to medical reasons, I am unable to use the computer for an
unknown amount of time.  When I have the OK from my doctor, I
will try to get back to you in a reasonable amount of time.

Sorry for any inconvenience.

Looking into old reports (finally ;-),

This doesn't appear to be related to ftrace, but instead for stack traces, which is something different than what the "trace" option is used for.
