Fixing recursive fault but reboot is needed!


Hi all,
I am frequently getting messages from kernel
"Fixing recursive fault but reboot is needed!"

I want to debug this. Which of the kernel module causing this? What is the rip and rsp and what is the call stack? HOw can i do this?

Dmesg only shows message
Fixing recursive fault but reboot is needed!
Fixing recursive fault but reboot is needed!
Fixing recursive fault but reboot is needed!

But this is not useful.

Thanks
Viral

It's in kernel/exit.c. In the moment it is printed thing are already wrong, so you need to get debug from before that moment. It is most likely caused by a driver. So turn kernel debug to higher level and wait for that situation to happen.

How can I turn on kernel debugger to higher level ?
I know only kgdb but then it requires two setups and so its tiresome for kernel debugging...
