I released another version of my tree .. It's still based on 2.6.22.1-rt4 . It's even more bisectable, but still not fully bisectable. I included the two fixes I post earlier today, [PATCH -rt] temporary WARN_ON removal [PATCH -rt] drop spurious rcu unlock Here's the combined patch, ftp://source.mvista.com/pub/dwalker/rt/patch-2.6.22.1-rt4-dw2 And the broken out set, ftp://source.mvista.com/pub/dwalker/rt/patch-2.6.22.1-rt4-dw2-broken-out.tar.gz The release notes for 2.6.22.1-rt4 also apply to this patch.
