Hi ,

What are the best tools to trace  linux kernel  panics and system hangs for linux kernel . please recommend for x86 as well as arm platforms .

I think, stack dump function inside magic sysrq is your first bet here... of course, it might not working on some cases (e.g: too much stack corruption). And don't forget to compile your kernel with debug info and frame pointer enabled...without that, stack dump will have hard time to convert addresses into meaningful symbols and back tracking stack frames. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
