Download Ubuntu kernel patches

I need to compile kernel 2.6.38-8 on Ubuntu 10.04.2 LTS. I downloaded kernel's source code from kernel.org, copied default configuration file for kernel 2.6.38-8 from Ubuntu 11.04, compiled and installed kernel. After loading Ubuntu 10.04 on kernel 2.6.38-8 some errors appeared. Realtek 8169 and Intel HD (driver: i915) doesn't work properly but when I launched Ubuntu 11.04 such errors didn't appear. I suggest problem with hardware rise up because I didn't apply some Ubuntu specific kernel patches.
When Ubuntu 10.04 is started with kernel 2.6.38-8 such errors appear:
