|  I would guess the issue with the actual subject of this PR is related to
|  the default ellision of COMPAT_FREEBSD from i386 GENERIC kernels some time
|  ago.
|  
|  I've seen similar errors but on my sparc systems and so far as I can
|  tell only during boot (right after root file system type determination).
|  I think there are other situations which trigger these messages during
|  normal operation, but I don't recall now what they are.  I don't notice
|  any loss of function on the system as a result, however.
|  
|  It only happens with my custom kernels from which I've removed all
|  COMPAT_* options (as I don't need them for my usage).  In my case, the
|  messages are as follows:
|  
|  [...]
|  kobj_checksyms, 882: [compat]: linker error: symbol `esigcode' not found
|  kobj_checksyms, 882: [compat]: linker error: symbol `sigcode' not found

This means that the the module is missing required symbols. You can
repeat this ad-nauseum manually by running 'modload compat' or the name
of the module that is failing. The fix is to add the missing symbols, files,
dependencies etc. to the module.
