Looks like your compiler is generating 64-bit division which is a call
into libgcc. Which gcc version are you using?
+ext4 folks.

Other two new kernel built fine, and all the previous 3.0.x kernels
have build using the same .config on system.
It is a quad core phenom II machine running Fedora 14 with the
