No, as I told you in a previous reply, linking the *kernel* with
-defsyms __Stacksize=a_larger_size is not necessary. It has *no
effect*. It is *user programs* that should be linked that way
to get a larger stack than the default 16k.
Sorry, I don't know right now whether there is an easy knob to
tweak when low stack in the kernel is a suspect.
