Re: Backtrace of every the threads

I did not explain myself well. By thread I mean kernel thread, and user thread. What i want to get is a back trace of ALL the programs running in user and kernel space. Your example is a single program, and the trace ends in userspace. Sorry for the missunderstunding. On Wed, Feb 10, 2016 at

Hello I have been debugging a process that makes a syscall which never returned. The problem was the interaction between than process and other kernel threads, due to an error on the way the locks were designed (my bad). Luckily, the error is gone now :). but I was wondering if there is a way to
