When upgrading, the first thing you must *always* do is to install a new 
kernel.  You appear to have installed a new system library (and possibly 
some new utilities) that use the new calls into the kernel that aren't 
supported by your existing kernel.

You may be able to rectify the situation if you remove the latest copy of 
libc.so that you have just installed (but be careful, you might end up 
with a completely dead system if your old libc is not there, or if you 
have installed new utilities that rely on it).  If not, your only recourse 
is a backup of your old system (you do have one, don't you?), or to 
download a ready-built snapshot and install that.
