Hi!

Does anyone know of some good ways (or any ways) to get kernel
backtraces from a linux kernel?

I have tried using/calling the function show_trace_task() and it seem
to work on all threads except the "current" thread which is the thread
I'm interested in.

I'm using 2.4.18 kernel.

You want a trace on the kernel part or user part? For kernel part, the
back trace you can find in
arch/i386/kernel/traps.c, but for user space part, a glibc API
backtrace() is provided, but not very powerful, the gdb can help do
the backtrace much better.
