wpa_supplicant and system tap

[Jack Smith]

I am trying to understand why my Wireless network connection is so
unstable.

I was wondering if it would be worthwhile to explore what ipw2200 is
doing by way of system tap.

Is this a sensible approach ?

If not, can you suggest a better one.

Thanks,
Jack

I never find system-tap useful for debugging modules, adding printk
in the code, recompiling and reloading module is much faster/better
method for me instead of writing stap scripts.

Many modules, including ipw2200, have "debug" option, using it is a good
idea when starting debugging. At some point, when more or less problem
is localized, adding custom printk's for getting more detailed
information is usually needed as well.
