I compiled the Linux 2.6.27.6 kernel on Ubuntu 8.10 with gcc (Ubuntu
4.3.2-1ubuntu11) 4.3.2.

The kernel doesn't compile cleanly, the compiler throws warnings.

Your compiler appears to be faulty. You should report this to Ubuntu

The warnings are valid (they're coming from -Wformat-security) but I
don't believe those warnings are normally enabled in kernel compilation.
Presumably some Ubuntu gcc patch enables them by default.
