--- Comment #3 from Daniel Vetter <daniel at ffwll.ch> ---
Hm, module reload should dump much more information when the dmesg verbosity is
correctly set over netconsole. So I still think there's something wrong with
your netconsole setup.

Can you please check whether your netconsole setup works correctly (= you get
the same output over netconsole as if you grab the dmesg output locally) on a
machine where module_reload works? If that works please check the netconsole
output of the affected hsw machine with another test which is know to put debug
information into dmesg but doesn't crash the machine, like testdisplay.
