Eduyptula task 2 doubt.

Hi, I got kernel from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git and build and booted my kernel with CONFIG_LOCALVERSION_AUTO set and uname -r comes out as 4.8.0-rc5-42-desktop and even the git tag list v4.8-rc5 as the latest but still penguin did not accept my task just wanted to know is penguin correct and I need to focus on getting the latest linux source or this is penguin issue. Please kindly let me know I have submitted twice to penguin but he does not seems to be happy. Regards, Vipul.
