But as of now there are few issues with "gdb bt"
1) Sometimes the no. of stack frames displayed doesn't end for a long time
and also the "q" command doesn't work as desired once the screen is
full.
The workaround is to give some limiting count like "gdb bt 10".
I tried gdb ver 6.1 externally (outside crash) also and see the same
long ending stack frames where as the latest gdb (ver 6.4), works fine. So
just wondering if you are planning to upgrade embedded gdb to ver 6.4?
2) As unlike crash, there is no concept of tasks in gdb, we can only see the
backtraces for tasks active at the time of crash.
I guess, we will continue to have both the backtracing mechanisms. I am
assuming that this approach does not disable crash's bt mechanism. Its
kind of add on? So a user can use crash bt mechanism for backtraces of
tasks which are not currently running on some cpu.
