Antti,

On my console and in /var/log/messages, I find

  WARNING: module error: use -f to reinstate builtin module "compat"

For example, whenever I type my login:

  login: dyoung
  WARNING: module error: use -f to reinstate builtin module "compat"
  Password:

I noticed that modstat tells me that REFS == -1 on some modules:

NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
compat           misc       builtin    -1    -        -

Does it have something to do with your change?

Dave
