Latest updates broke my system (URGENT)

[Antonio M]

After latest updates (including Xserver, kernel, selinux policyof my
server, I set Selinux to enforced (immediately after updates) and I
couldn't log in graphically, I get the message the login was too
short, some errors in Xlof file saying that daemon hald (not sure
about it, maybe some bus, I am not sitting at the computer now....) is
not started

How do I recover my server????
