"I have no name", etc. after hibernate

[Pekka Savola]

Hi,

On F12, as of about 1 month ago, user information started getting lost 
sometimes after resuming from hibernate.  You can see this as follows:

- With new terminals, the prompt user name is "I have no name!".
- With new SSH sessions, you get "You don't exist, go away!"
- "Su" fails with "su: user root does not exist"
- You can't login from new VTYs (just fails)
- "ls" does not look up uids/gids

/etc/passwd is 644, and usernames do exist there.  LDAP auth is not used. 
Selinux is permissive. nscd is off. I do use fingerprint reader for auth but I 
doubt that's relevant.

I couldn't find anything in bugzilla, and I have no idea which component to 
file this against.  Any ideas?
