Specifically, the lnc driver declares NLNC softcs. Mark has an isa
style ``device lnc0'' in his config and then uses vmware with two
configured devices.
config <kernel> produces lnc.h which contains ``#define NLNC 1'' and
if_lnc_pci.c dives in and starts writing to the second softc.
I'll look at fixing this at some point if you don't have time Paul :-I
This may have broken because Paul changed the softc decl from static
to just global (so that the other if_lnc*.c modules can get at it)....
either that or Mark has been ``just lucky'' so far and the lnc driver
has never worked properly with more than one device. This would neatly
explain why he's seen funny errors in the past - one of them was a
message to you Garrett saying that your npx.c modification to do no
more than output a boot-time diagnostic seemed to screw up his
kernel !!!
