[yocto] Out-of-Tree Modules and __stack_chk_fail()

[Daniel.]

Ronald,

Was the kernel compiled with -fstack-protector?

Try running this on target:
cat /proc/kallsyms | grep __stack_chk_fail
Does it output the symbol address?

Take a look here: http://lxr.free-electrons.com/source/kernel/panic.c#L558

Best regards
