I can confirm that this patch fixes the issue for me on the mx28 board. Before the patch transmitting a linux kernel archive failed many times. With the patch applied the file was transfered successfully with the first try.

Used gcc version: gcc version 4.5.4 20110808 (prerelease) (Linaro GCC 4.5-2011.08)
