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

That resolved my problem. (And while I was at it, I found that I had
failed to create a new .bbappend file to pull my custom kernel config
file in when I had to change to an older kernel version due to kernel
versions supported by the vendor - so I had none of my other kernel
configurations either

Any ideas how to proceed?
1) Can you try to use it from an in-tree kernel module? (modify the

2) Can you grep in your kernel config for
CONFIG_CC_STACKPROTECTOR and friends?

Furthering my investagation into why my vendor supplied kernel modules
were failing to load due to the error "Unknown symbol __stack_chk_fail
(err 0)," I conducted the following experiment:
1: I took the sample code from
poky/meta-skeleton/recipes-kernel/helo-mod and moved it into a new
layer as m
