No, for some reason my other box doesn't want to boot your config (no root found). But I noticed that my first box fails on tip/master with just my min-config. I ran the bisect and hit this as the bad commit:
commit 41e95d95208c62d4b0fbcee5f16d93e23ca32984 Author: Ingo Molnar <mingo@elte.hu> Date: Thu Sep 17 23:12:20 2009 +0200
<not-for-merge> Disable DEVTMPFS_MOUNT for now
Causing bootup problems - /dev/zero and /dev/null not being there, etc.

When I reverted this, my machine booted. I'm now trying that machine again with your allyesconfig.
Is there other strange things in tip/master that I should be aware about?
Again, do you see these errors when just booting my branch directly? (not merging the branch into another branch).

Hmm, your right. It depends on dyn_ftrace to be configured. Strange that my tests didn't catch that as I thought one of my tests compiles with static ftrace. I'll have to look into why my test didn't catch that. I'll send a fix later today.
Thanks,
