FreeBSD 9.0 hang

[Doug Hardie]

I have a 9.0 p3 system that is in production for about a week and it just plain hung this morning.  The console had the last two messages as:

link_eif symbol atm_event undefined
KLD if_en.ko: depends on utopia - not available or version mismatch.

I haven't found anything relevant on those through Google.  if_en.ko os present as is utopia.ko.  I don't understand why the kernel would try to load if_en as I don't have any of those devices.  There are em0 and dc0 ethernet interfaces.  This is almost a generic kernel.  The config file contains:

include GENERIC

ident           LAFN

nocpu           i486_CPU
nocpu           i586_CPU

options         QUOTA
#device          atapicam
options         ALTQ        # Enable ALTQ.
options         ALTQ_CBQ    # Build the ``Class Based Queuing'' discipline.
options         ALTQ_NOPCC      # Required for SMP build


I couldn't find any relevant log messages that would indicate why this module was trying to be loaded. However, even so, I would think it should load ok.
