I can boot with the latest linux-omap version, but as soon as I enable omapfb, kernel freezes before making any output to the serial console. Have I missed some DSS/DPI patches? After some research I found out that only the master branch is broken. At least rc7 is O.K.: git checkout v3.3-rc7 master freezes: git checkout origin/master According to commit log (http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap.git;a=commitdiff;h=b8fe1781ec8bed5e086691a827a6ee11facec2aa), there is nothing suspicious. How can I see the real difference between v3.3-rc7 and master branch? Is this command sufficient? git diff v3.3-rc7..origin/master Yegor
